Re: A degree from US. Is it worth the time & money?
I just took the GMAT a few months ago.
First, forget Kaplan. It's a good intro to how the GMAT works (timings, format etc) but I found that their questions were different from the actual exam.
1) Go to GMATClub or beatthegmat and read the intro guides. A lot of good info there. Free tests, study guides etc.
2) My recommendation is to buy the Official Guides (OG) and the Manhattan guides and do them, do them again, and if you have time, do it one more time. And most importantly, go through and review each mistake you made. This is more painful than actually doing the problems but that's how you actually learn. Again, make sure to review the problems. Even the ones you got right. There may be a more efficient way to solve it and efficiency and time management is everything on the GMAT.
Also, you can download an excel template for the current year's OG questions from beatthegmat.com. This way, you can just enter your answers in the spreadsheet and it will give you a breakdown of how many questions you got wrong, as well as what type you had problems with.
3) You can download software from mba.com (official GMAT website) which gives you two practice tests. My advice would be to do one test before studying or after a few weeks, to see where you are. Do the other test closer to your actual date. You can uninstall the program and retake the two tests but you're likely to see a few repeated questions. If your score increases a lot then you might see entirely different questions!
4) Go to the websites I mentioned above to get some free practice tests. I found the two free official tests to be the most realistic. You can also get a free Manhattan test. The math on the Manhattan test is a bit tougher but their tests show you the breakdown of each question. I would also recommend purchasing practice tests from Manhattan if you have time to do them.
The more practice the better. I underestimated how important this is because my attitude was that given enough time, I can solve any question. While this is true, the problem with the GMAT is that you don't have enough time. You have to move *on every question. I improved my score about 40 points just by finishing each section. If you spend 30-40 seconds and don't know how to even begin, guess and move on. If it's been 1-1.5 minutes and you are having trouble finishing, make an educated guess and move on. Trust me when I say, time management is everything. Whatever you do, **do not spend 4-5 minutes on any question*.
Oh and I got a 700. I was a bit disappointed but like I said, I underestimated the difficulty and had to cram the last two weeks. PM me if you have any questions.
