Hi Aji,

I've moved your question to the SC forum, where you can get more feedback from a variety of experts.

I agree that SC questions in which all or most of the sentence is underlined are more challenging than those that have only a few words underlined. Here is my advice:

1) simply allow yourself more time on these. Not every SC question needs to be done in the same time frame, and you really can't move through these quickly and still maintain accuracy.

2) you won't be able to "read vertically" and compare individual words, as you can when only a few words are underlined. You'll need to change your strategy a bit.

3) instead, focus on identifying the topic being tested. Do you notice parallelism or comparisons? Subject-verb agreement? Don't rely on splits between answer choices to tell you what's being tested. Try to identify that as you're reading the sentence.

Taking notes while reading the question will waste time. Re-reading also wastes time.

4) I agree with the first statement, but I do not agree with the second. I re-read almost every sentence with a long underline! First, read for the gist of the sentence. Then go back and look at the structural pieces.

5) Review deeply. That's the best way to improve - pick apart every practice question you've done in detail, and start tracking your errors. Are you missing modifier issues most often? Or pronouns? You can then train yourself to look out for these things.

Good luck!

Most importantly, make sure that you know your grammar rules, and that you're not just relying on your ear. Here's an explanation for why a good ear isn't good enough: https://www.manhattanprep.com/gmat/blog ... orrection/
