CR-1 can’t be C, it is in favour of plan not working out, we need to find the one in which it works

if you indicates critical reasoning, you can it in practice question bank or go to CR forums. "GMAT>Practice question banks>select types of questions>search" or Forum>Verbal questions(CR)

How is the difficult level of next questions affected when the previous question is marked for review? If I mark all 3 MSR questions for review and come back to those at the end... will this reduce the overall difficulty level of my section?

It’s a good question. Unfortunately we don’t know yet. There are several ways to influence an adaptive algorithm in a test where and choices can be changed and similarly thorough ways to counteract these hacks. The reality however is that because the test database is limited, even if you get an arithmetic question right in quant and your next question should be harder algebra question but the database has only easy algebra questions, you’ll get an easy question similarly if you get the question wrong and you’re supposed to get an easy probability question, but the database only has hard probability questions, you’ll get a hard probability question so there is variance in question difficulty simply because of the database size. Back to your question, GMAC claims that supposedly the three and choices don’t impact the final score but who knows for sure…. Ultimately we haven’t been able to get enough information about the algorithm to determine or to get a good understanding of it like we had in the version of the test. Personally, I wouldn’t worry too much about how the difficulties determined and focus on how you can get as many questions answered correctly as possible.

It seems like it would be a game of chance then. Sometimes it does feel like the initial questions are harder than the later questionz A lot of times actually
