Excellent - nice job!
Also, I got higher raw scores in both Q and V from my MGMAT CAT2 but still got the same 690 score. I found that odd.
Can you check what you posted above? According to what you posted, your Q went down a little on the real test (46 to 44), but your V actually went UP one point (from 39 to 40). So it actually makes sense that you'd get the same (or a very similar) overall score.
Re: improving from a 690 to mid-700s, at this point, I wouldn't worry about getting a ton of new questions to do. What you need to do is pick apart all of the questions you already have, to the point that you could teach them to someone else and almost even write one yourself! (This is if you want to get a mid-700s score.)
Having said that, you can get some new official questions via OG12 (just published a few months ago) and GMAT Focus (quant only and online only). But don't start with those - save those for a couple of weeks from now.
Go back to problems you've done already (all of them, whether you got them right or wrong) and ask yourself:
Was I able to CATEGORIZE this question by topic and subtopic? By process / technique?
Did I make a CONNECTION to previous experience? Or did I have to do it all from scratch?
Did I COMPREHEND the symbols, text, questions, statements, and answer choices?
Did I understand the CONTENT being tested?
Did I choose the best APPROACH? On quant especially, there are almost always better / more efficient ways if we study the problem!
Did I have the SKILLS to follow through?
Am I comfortable with OTHER STRATEGIES that would have worked, at least partially? How should I have made an educated guess?
Do I understand every TRAP & TRICK that the writer built into the question, including wrong answers?
Have I MASTERED this problem? Could I explain every aspect, fully, to someone else?
How will I RECOGNIZE similar problems in the future?
On ALL verbal questions, ask yourself:
- why was the wrong answer so tempting? why did it look like it might be right? (be as explicit as possible)
- why was it actually wrong? what specific words indicate that it is wrong and how did I overlook those clues the first time?
- why did the right answer seem wrong? what made it so tempting to cross off the right answer? why were those things actually okay - what was my error in thinking that they were wrong?
- why was it actually right?
If you're studying a problem you got right, then pick the most tempting wrong answer and answer the questions above accordingly.
After you start getting really good at understanding / doing all of the above, then start testing yourself with new official questions. :)
