Hello Thanhtnguyen94
We appreciate the start with 640 (Q 39, V 38) and wish you best luck. The score seems to be decent and well balanced. As you have already collected some books and targeting 730+, we will like to recommend certain key points which will be helpful.Various possible combinations that you should keep in mind to achieve a score of 730 or above are:
V37/Q50, V39/Q49, V43/Q45 are some possible combinations.
GMAT is not as easy as we assume. GMAT math is logic, and GMAT verbal is a real test of English as a language. GMAT learning is a continuous process. Initially, you should spend more time on learning basic concepts and try solving as many as questions you can.
Build your math basics with our "Math Review" (5-hour lesson). These videos are for reviewing basic math, including arithmetic, algebra, geometry, and word problems. You may take an online course where you may ask as many questions you have, or you may consider private tutoring as well. A start with Q 38 is good which should be raised to at least Q 45 or above to score 700+.
