The 2015 vs. 2016 PowerScore LSAT Logic Games Bibles

2016 Logic Games Bible

The 2016 PowerScore LSAT Logic Games Bible is out!Every year, we release an updated version of the LSAT Logic Games Bible, including the 2016 version.  We do this to account for changes in the test, to expand and clarify certain explanations, and to add new and refreshed content in order to keep the books as useful as possible. Because of the extent of these yearly changes, one of the most common questions we get each year is: can I use an LGB from a prior year to study for this year’s LSAT? Sometimes the answer is yes, and sometimes it is no. This year, the answer is no, so please allow me a moment to explain why.

New vs. Old Bible

First, if you’ve bought a new Logic Games Bible in the past several months from us or a major retailer such as Amazon, you should already have the 2016 version. We typically begin shipping the newest version of the book as soon as it arrives so that students automatically get the most updated version. However, with the prevalence of other channels such as eBay and Craigslist, sometimes students end up with older copies. If you have an older version, there’s nothing “wrong” with it, and the advice therein won’t hurt your score. When we release new versions, what we attempt to do is make them easier to use and more comprehensive. The newest version is always the most optimal vehicle for learning Logic Games, and the revisions I make are partially based on student suggestion, so each year the books get easier and easier to use.

Diagramming

In some years, the changes are very noticeable (for example, in the 2013 version, I added 228 pages, creating a very different book). The changes to the 2016 version are equally noticeable, but less so due to content additions. This year, we made extensive changes to our Sequencing Diagramming approach, a change that we made at all levels of our LSAT preparation, including our courses. I’m going to first explain the nature of the changes, and then discuss why we made them.

For years, we’ve used a sophisticated sequencing approach that featured the “>” symbol. I didn’t use this symbol to convey numerical value, but rather to convey items that were to the left or right of each other. Thus, J > K simply meant that J was to the left of K, or that J appeared earlier in the lineup. The “>” symbol was a great tool because everyone knew that “>” meant relative positioning, and so it made it easy to understand that if J was second, then K could be third, or fourth, or fifth, etc; in other words, that J and K would move relative to each other. Over the years, we added some additional symbols in order to account for testing wrinkles that LSAC added to the test, and created a system that was extremely comprehensive in its ability to capture sequencing relationships.

Sequencing Games

However, the LSAT isn’t static, and in the last year or two, I’ve noticed LSAC doing something different than in previous years. They started creating Sequencing games that relied far more on variables that are common to multiple chains but aren’t fixed in position. Previously, they rarely did this, but in order to combat this change, I felt we needed to refine our system. And so we did, transitioning to a new representation for Sequencing rules that I feel can better account for this uncertainty and complexity. We obviously tested this system out prior to implementation, and the returns were excellent: students felt more comfortable and they were better able to handle some of the tricks LSAC was throwing at them. However, this meant changes on over a hundred pages of the LGB, and in multiple chapters of the book. Hence, the 2016 version looks and feels different than any prior version.

Some students have asked me if this change on our part is unprecedented. Not at all. The battle between test makers and test preparers has been going on for years, and we make changes all the time based on things they do. That won’t change, but it highlights one reason why I feel that the most up-to-date versions of our books are so important to have: they contain the most cutting-edge materials available, and they give you the best possible opportunity to destroy the LSAT.

    Hi Dave,

    Thanks for your information on 2016 LG bible. I have 2014 LR/LG/RC bibles now, and I am going to study LSAT again, and I plan to buy 2016 LG bible given the differences.

    I was wondering how about 2016 LR and RC bibles? Are they different from 2014’s enough, so it is better for me to buy 2016 version?

    Thanks,
    Brandon

    Hey Brandon – thanks for the question! Dave’s traveling at the moment, so I thought I’d jump in here and hopefully help you out 🙂

    There have been some updates to both the 2014 LR Bible and RC Bible, although neither are to the same extent as those made to the LG Bible.

    More specifically, the LRB has seen a revision to the section on Parallel Flaw questions, expansions to the Question Identifiers section (question type breakdowns), clarification about sufficiency and necessity in Justify and Assumption questions, and perhaps most critically an additional 4 pages of content on Numbers/Percentages questions.

    For RC, we’ve added a full section on Inferences and Assumptions, and expanded a large number of the book’s drill sets.

    So I think you’ll find that, as Dave says, the 2014 editions aren’t in any way wrong or misleading, but merely slightly less expansive than those issued for 2016. It’s a tough call as to whether the additions/expansions mentioned above are worth the purchase of brand new books, however, particularly if you’re performing well in LR and RC already with the content you have. I think if I was in your position I’d lean towards spending that money on the LR and RC (and even LG) Workbooks, so that you get something that’s both filled entirely with novel content, and that allows you to continue reinforcing the conceptual ideas you’ll encounter in the Bibles.

    I hope that helps!

    I have the Bible trilogy of the 2015? In all honesty, beside buying a new LG Bible, are the other two new Bibles that necessary or the 2015 material of LR and RC will do?

  • Dave Killoran

    As I’ve mentioned elsewhere, and intend to cover in a blog very soon, the LGB is the one that needs to be the 2016 version if you are taking the later LSATs the year (September 2016 and December 2016). If you have the 2015 versions of the LRB and RCB, you will be fine. While improvements have been made in the LRB and RCB, they aren’t enough to justify the additional cost.

    Thanks!

    I have the 2012 version but plan on purchasing the 2016 version soon. Is it ok if I start using the 2012 bible versions for a few weeks until I purchase the 2016 versions? Also, I plan on taking the LSAT June 2017. Does this mean I will have to purchase the 2017 prep versions? Thanks

  • Dave Killoran

    Hi Linda,

    Thanks for the questions! Yes, you can use the 2012 versions as starters. The 2012 and 2016 versions are quite different, but nothing in the 2016 versions contradicts any thing in the 2012 versions, so you won’t be learning anything “wrong.”

    With the 2017 versions, you either won’t need to buy any, or only one or two. I won’t know for sure until I start making those changes, but i will announce what changes are made. For the LGB, I don’t foresee changes significant enough to cause you to have to buy a new book. The LRB is a bit less clear, and the RCB is the one I suspect will change the most. As you may have seen elsewhere, if I don’t feel the changes are significant enough, I won’t recommend upgrading. I know how expensive these books are!

    Please let me know if that helps. Thanks!

    Hi Dave,

    I’m in a similar situation as Linda, I plan on taking the LSAT in June 2017.

    I want to start studying in January 2017 and obviously will be using the PowerScore Bibles.

    I always want the new and updated versions so my question to you is: When will the 2017 versions be released? I don’t want to delay by studying time by a month if the 2017 version get released in early 2017 (in that case I will just use the 2016 versions).

    Thank you.

    Hi Meghan,

    Thanks for the question, and thanks also for being a student of ours–we really appreciate it! The 2017 versions will be released towards the end of this year. An exact date has not been set as of yet, but the usual target date is the end of November. I always wait until after the September LSAT is released so I can incorporate any changes inspired by the questions on that exam.

    Please let me know if you have any other questions. Thanks!

    It should me thanking you guys – it would be a stupid decision not to learn from the Bibles!

    Thank you for your response to my question! I’m going to look forward to buying the 2017 versions and learning from your changes.

    Again, thank you very much.

    Is there a significant difference between the 2015 and 2016 workbooks?

  • Dave Killoran
    July 02, 2016 at 5:50pm

    Hi Madison,

    Thanks for the question! We make ongoing improvements to all of the workbooks, but you can use last year’s versions and you should be just fine, if I recall correctly. The RCBW had some changes, and on Tuesday I’ll access those and double-check them. If the changes were significant enough to suggest that a new edition would be necessary, I’ll post back and discuss that with you. but off the top of my head, I think you will be fine with last year’s workbooks.

    It won’t affect you, but for 2017 students, I believe that at least one and possibly two of the Workbooks will undergo a revisions significant enough to warrant the newest edition. I’ll announce those changes when they occur.

    Please let me know if that helps. Thanks!

    I’m an LSAT student from Puerto Rico looking for the best way to prepare for the Logic Games section this upcoming 2017. I unfortunately can’t afford the particular costs of shipping the 2017 logic games bible through UPS (the only option available on the Powerscore platform) and was looking to instead use my student Amazon prime account to prevent some of these debilitating costs. However, on that platform, the only available edition is the 2016 one. I was wondering if there was any timeline for releasing the new edition on Amazon so I can better prepare for my 2017 LSATs. Thanks!!

  • Dave Killoran
    December 06, 2016 at 4:27am

    Hi Eduardo,

    Thanks for the message! While we don’t control what Amazon does, I would expect they should be switching over pretty soon. I’ll see if I can get a specific answer for you but I would suspect it will be within a month or 6 weeks at most. If that’s not the case, I’ll post back on what I find.

    Thanks!

    Ok,I have a question similar to everyone else. In December 2015 I bought all Power Score material (Bibles and workbooks), 2015 edition. I was planning on taking the LSAT in 2016 but was sidetracked by other things. I am now planning on taking the 2017 June LSAT, do I need to buy new material or does only a portion of what I have need to be replaced?

  • Jon Denning
    December 15, 2016 at 10:29pm

    Hi Aziér-di – thanks for the question! Let me give you my thoughts on each of the three Bibles, comparing 2015 editions to the just-released 2017 set. Note: a lot of this will echo another of Dave’s blogs where he outlines the advantages of the 2016 collection over prior versions (http://blog.powerscore.com/lsat/the-2016-lsat-bibles-do-you-need-the-new…)

    Logic Games Bible

    You should upgrade. The 2016 update was a huge one, so getting either the 2016 or 2017 LGB will offer significant advantages over your current, 2015 book. I won’t go into the specifics of what all changed since this very blog details those changes, but suffice it to say that the updates are notable and worth the money to obtain. The differences between 2016 and 2017 were less substantial so if you go with 2016 to save a few bucks you’d be alright, or jump to 2017 and get the latest and greatest 🙂

    Reading Comprehension Bible

    Again, I recommend an upgrade, although make sure it’s the 2017 edition. The just-released RCB has a ton of useful updates compared to previous years. To quote the author (Dave Killoran) himself: ““In the 2017 edition, I expanded the focus on how to approach and deconstruct passages, and how to better use the analytic tools we provide in the book. I also added new content on what to do in situations where you are struggling, including a lengthy discussion of alternate strategies and how and when you’d want to implement those. My goal was to increase the ease of applying the powerful techniques presented in the Bible, to give readers a clearer sense of how to operate within passages and control the natural uncertainty they may face, and to provide an additional set of tools to use if a passage or a section is becoming overwhelming. This edition is a clear step up over previous versions.”

    Logical Reasoning Bible

    This one is a tougher call, but if purchasing new editions of Games and RC is straining the wallet I think you can hold off on a new Reasoning Bible. There have been some changes made since 2015, but nothing like what was done in 2016 for Games or 2017 for RC. The biggest change in recent years to this book happened in 2014, so you have a version that’s mostly current (again, a number of tweaks and expansions have occurred since yours came out, but nothing I’d say makes upgrading a must). As always though newer editions are better, so if you have to have the very best then a new LRB is the way to go. Overall it’s the third most important at this point, though.

    I hope that helps!

  • Aziér-di Oxendine

    Hi Jon, thank you so much for your response. I see that it is a must to get the newer material and will upgrade ASAP. Let me ask you, did the Training Type Trilogy books get a revision also? If so, do I need to get an upgrade on those as well?

  • Dave Killoran
    December 20, 2016 at 8:22pm

    Hi Aziér,

    Thanks for the question! I thought I’d jump in so you could get a response asap. With the Training Type books, those are question collections from past LSATs divided into categories such as Assumption questions, Weaken questions, Causal questions, Formal Logic, etc, and as such they do not change from year to year (which is why there are no yearly version indicators on those books). So, you do NOT need to get new copies of those books–the older versions are just fine!

    Please let me know if that helps. Thank you!

  • Aziér-di Oxendine
    December 21, 2016 at 7:26pm

    Hi Dave,

    Thank you for your response; it helped a lot! I will get the updated bibles/workbooks and let my study journey begin.

    Thanks,
    Aziér-di

    Hi Dave,

    I have the 2017 RC, LG & LR and was wondering if I should order the 2017 versions of the Training Type Collections & Workbooks or the 2018 version to coincide with the study plans provided.

  • Dave Killoran
    July 04, 2018 at 4:33pm

    Hey Tony,

    Thanks for the question! If you haven’t ordered yet, get the 2018s. They will work with the study plans and 2017 Bibles, and we always make a few changes every year so it’s better to have the most up-to-date ones.

    Thanks for using our books, and we’re here if you have any questions!
