No there isn't a way to upload screen shots, etc. We won't actually do the full analysis for you on the forums (that's something that would be paid, like tutoring). But we will help you analyze yourself. :)
I actually know the content (everything was familiar to me) but during the CAT I was missing the "first idea"
Okay, then that's what you need to study. What are the clues that should have given you that "first idea" - that way into the problem? Go back to problems you have already done and ask the 2nd level questions that are about how to understand what they're really asking and come up with a good plan / approach.
Eg, now that I read the solution, I can see that I could use smart numbers (pick or plug in my own numbers), but I didn't think of that when the problem first came up. So what are the clues in the set-up of the problem itself that should have triggered the thought, "Hey I can use smart numbers here!"
Those clues are consistent. I'm not going to tell you what they are right now. Try to figure it out. You can look at the article below for ideas if you get stuck. Or, if you have our 6th edition books, you can look it up in one of the strategy chapters. If you'd like to check your understanding, explain this to me in your next post.
https://www.manhattangmat.com/blog/2013 ... er-part-1/Yes, the second level of learning absolutely applies to CR and RC.
For instance, I know the various ways to identify Find the Assumption questions. I know that FA arguments will contain a conclusion, at least one premise, and at least one assumption bridging that gap (usually multiple).
I know that my goal on FA is to find something that the author must believe to be true in order to make the argument that he's making.
And I know that some traps will do things like strengthen the argument, but via something that doesn't HAVE to be true. And I know all of the above the instant I recognize that a problem is FA.
For instance, I teach OG 2015 CR #46 in class. Go try it, then read what I have to say about it below.
This is FA because of the word "assumption" in the question stem (so this one's kind of obvious). The specific argument is "institute fee --> people will throw out less trash to avoid fee --> we will save parkland" and the last thing is the final conclusion. This overall kind of argument, though, is what we call a "plan" and the overriding assumption is "the plan will work the way I say it's going to work."
Now that you know all of that, how does the correct answer fit into the last thing that I typed? And how could you use those ideas to do similar CR FA plan questions in the future? Let me know and then I'll let you know what I think. :)
For your vocab / small detail issues for CR and RC, start doing some non-GMAT reading every day - articles from New York Times, Wall Street Journal. That will expand your vocab and the kinds of idioms that you'd want to make sure you know. If you've got a friend who's very good with reading comprehension-type stuff, ask him or her to read the same things. You describe what you read and see whether your friend has the same interpretation.
Okay, now on to your timing problems.
First, there's only one good reason to have a really-fast-and-wrong problem: because you knew you didn't know what to do. You don't want to miss something that you knew how to do because you rushed and made a careless mistake
Next, everything that you do uses some amount of mental energy. The harder it is (and the longer you spend on it), the more mental energy you use. So when you get something right in 3.5 minutes, that's actually not a good thing, because you used the time AND mental energy for two questions to answer just one. It's better to get that question wrong in less time and spend that time and mental energy on things that you are more likely to get right (especially because, if it takes 3.5 minutes to get the question right, then it's really hard - and there's a strong chance you'll make a mistake or not be able to do it anyway, just because it's so hard).
Don't forget that your mental energy is just as limited as your time. Once you start getting too tired, you're going to make a lot more mistakes and your score is going to go down.
So, in general, you don't want to spend more than about 45 to 60 seconds above average time for a particular question, because the costs are too high
even if you get the thing right in the end.
Use these two articles to help you get better with timing:
http://www.manhattangmat.com/blog/2013/ ... -to-do-it/http://tinyurl.com/GMATTimeManagementUnder "Fill your buckets," you list "weak areas." Are these bucket 2 or bucket 3? There seems to be a mix of 2 and 3 here.
For instance, careless mistakes are bucket 2. But Circles & Cylinders sounds like it might be bucket 3, from the way you described it.
Start following this for careless mistakes:
http://www.manhattangmat.com/blog/2012/ ... -the-gmat/For NP, you describe having issues with testing cases. This strategy is described in the same article I linked earlier for quant: the 4 strategies to master. It's also described in some of our 6th edition quant books.
I'm less concerned about Circles and Rates because, from your description, those sound more like bucket 3 for now.
Oh, and I'm at the end and see that you're test is coming up soon (or maybe you just took it?). Let me know how it goes!
If you have to take the TOEFL anyway, then I do suggest that you do that first. It tests English at a more fundamental level, so you will work out all of those problems first, and that will help you with the GMAT.
Good luck, either way!
