You are correct that you're having timing issues on the test but, no, the best approach is not to guess randomly on 10 questions in the middle of the test. You are also correct that having to guess blindly on 10 in a row at the end is bringing your score down—but that will happen
anywhere on the exam if you have that many wrong in a row. It is not the case that the earlier or later questions are worth more (or that the middle ones are worth less).
You are going to guess randomly on some questions—but you are going to choose the *hardest* questions (hardest for you) as you seem them throughout the entire test. These are the ones that you are the most likely to get wrong or to take way too much time to get right—so these should be your fast guesses.
For example, you say that certain kinds of SC questions take you 1.5m, 2m, or 4m. The 4m ones are an example of the type that you should
get wrong faster. The test is not just asking you whether you can get these questions right—it's asking whether you can get them right in a reasonable amount of time. When you can, great. When you can't, the better decision is to get the question wrong faster—NOT to get it right while taking way too much time.

https://www.manhattanprep.com/gmat/blog/2016/05/26/develop-a-business-mindset-to-maximize-your-roi-on-the-gmat/Why did I ask you to look at those things? What did you learn? Are you actually taking the test that way? Or are you still using the old school mindset, trying to get everything right?
The good news: If you can learn to make better decisions about what to do and what NOT to do, your score will go up without learning anything new or getting better at any of the actual content. (And then you can also work more on actual content to try to lift even higher!)
If you took our course, then you're eligible for a free Post-Exam Assessment (if you haven't done it already). This is a phone call with an instructor to figure out what happened on test day and come up with a plan to re-take the test. If this applies to you, please send an email to
gmat@manhattanprep.com to request the Post-Exam Assessment.
If you did not take our course, we can discuss plans here. In that case, first, read these two articles (re-read in the case of the first one):

Then, use the below to analyze your most recent MPrep CATs (this should take you a minimum of 1 hour):
http://tinyurl.com/analyzeyourcatsBased on all of that, figure out your strengths and weaknesses as well as any ideas you have for what you think you should do. Then come back here and tell us; we'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Your analysis should include a discussion of your buckets—you'll understand what that means when you read the last article. Part of getting better is developing your ability to analyze your result—figure out what they mean and what you think you should do about them!)
