Hi gangeyyo,
To start, a 700 is a fantastic practice CAT score - assuming that you took this CAT in a realistic fashion, then this score implies that you have the capacity to score at a high level (the 90th percentile or higher) on Test Day - so referring to any part of it as "miserable" or "pathetic" makes you sound silly.
At this score level, if you're looking to score a lot higher, then you really have to 'nitpick' your performance to determine WHY you're getting questions wrong. If you're getting questions wrong because you don't understand the content, then that's one thing... but if you're getting questions wrong because of silly mistakes, then that changes what you need to work on.
While a full Mistake Tracker or
Error Log would be more detailed, there are some basic questions that you should look to answer. After reviewing each section of this CAT, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/verbal that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
Also, since you mentioned that you had studied before, was this the FIRST time you took this CAT (or had you taken it before?)?
