All GMAT Ninja Complete Sentence Correction Explanations
Welcome to part 2 in our attempt to tame the tangle of mayhem we’ve unleashed on the verbal forums over the years. Last week, we jammed
all of our full CR explanations into one post; on the thread you’re reading right now, you get to suffer through a list of all of our full SC explanations.
Lucky you. Keep reading for a bit of context on what to do with this pile of (digital) ink.
How to use these complete SC explanations
Warning: we’re about to echo a few things we said in our
compilation of complete CR explanations. If you already read that, we won’t be offended if you skip ahead here.
So here it comes again: memorizing our explanations -- or anybody’s explanations -- is a complete waste of your time, especially for verbal questions.
Why?
This might sound obvious, but no two GMAT SC questions are exactly alike -- and no two official GMAT SC questions are even all that similar. Sure, some general themes and concepts certainly reappear in multiple questions, but if you blindly memorize the EXACT thought process for a particular SC question, you’ll miss the point.
Nobody likes to hear this, but the vast majority of sentence correction errors happen when the test-taker either fails to catch the EXACT meaning of the sentences, or fails to notice specific flaws in some of the answer choices. A good, full explanation will point out those flaws in a nice, clear way -- and a good explanation will also break down the small nuances of language that are at the heart of GMAT SC.
If we do our jobs well as explanation-writers, you’ll easily understand why the OA is correct. But after reading our SC explanations, will you be in a better position to understand the EXACT meaning of a totally different SC question, or to notice the most important differences between answer choices? Probably not. You might pick up some good tips on how to structure your thinking, or how to think about the grammar or usage in a specific question. But studying our explanations won’t make you a better, more precise reader -- and it definitely won’t do much to help you figure out where YOU went wrong in terms of your process on GMAT SC questions.
Instead, here’s how we recommend practicing sentence correction -- or anything else on the GMAT:
- After you’ve completed a set of practice SC questions, don’t review your mistakes (or read an explanation) right away. Instead, wait a few days, and then attempt the question again, doing your best to forget that you’ve ever seen it before.
- If you easily answer the question correctly when you redo it, pay close attention to what you did differently the second time -- and work on making whatever went right part of your process EVERY time you do a SC question.
- If you miss a question a second time, then reading a full explanation might help a bit. But keep in mind that one of your main goals is to figure out where YOU went wrong, and how YOUR personal process can be optimized. So use our explanations as a tool for learning and self-discovery -- not as a strict, step-by-step recipe.
Also, if you aren’t confident in your overall approach to critical reasoning, you might want to start with our
beginner’s guide to SC, or
our mountain of YouTube videos. We also discuss self-study strategies in depth in
this video, and highlight a general approach to SC in
this video and
this one.
OK, rant over. Now, here’s the SC motherlode:

Old GMAT Verbal Review SC Questions (pre-2020)
And these exciting things are full explanations of SC questions that appear in pre-2020 editions of the GMAT Verbal Review guide, but not in the more recent versions:
GMAT Club Test SC Questions
If you’ve read a few of our forum posts, you probably know that we tend to discourage test-takers from relying on non-official GMAT verbal questions. GMAC spends literally thousands of dollars creating, testing, and perfecting each question that makes it into the exam; even the best test-prep companies can’t compete, and GMAT Club is charming and sexy, but (unfortunately!) no exception.
But if you’re here, odds are decent that you’re using the
GMAT Club tests, so the list below features full explanations of some of our favorite SC questions from the
GMAT Club tests. Full disclosure: we wrote or at least heavily edited most of these, but they’re still not perfect. So please take them with a grain of salt.
Also, if you still plan to take the GMAT Club verbal tests, we’d recommend holding off on reading these explanations -- they’ll definitely bias your results.
Official MBA.com (formerly known as GMATPrep) SC Questions
Please be particularly careful with these!
The six official mba.com exams are the next-best thing to the real GMAT exam -- and if you’re already familiar with some of the questions, you’ll warp your results in unfortunate ways, as discussed in
this article.
In other words: don’t read any of the full SC explanations on this list unless you’re SURE that you don’t plan to retake the mba.com exams.
