Sugestions For Gmat prep

During the week, focus on practice questions, doing one or two question types a night. Use the strategies in the PR book and the practice questions in the OG 11 book for this (rather redundant to have both OG 10 and 11, and 10 is out of date). Keep an error log as you go.

Spend perhaps 45-60 minutes doing practice questions of one type, then score them and log the errors. Then spend another 30 minutes working through the fundamentals or strategies that were lacking. Then take a break, and switch to another question type. Do this each night on weeknights.

Each weekend, take a full practice test. The GMATPrep and Princeton Review tests are the best ones because the questions and scoring are most like the real thing. The PR tests have answer explanations as well, so you can review and track your errors.

Review your errors on the test and compare them to errors you made while doing practice questions. If you're making the same types of errors, you likely need to work more on fundamentals. If you're getting questions right in practice but not so much on the timed tests, then you need to work on test-taking strategies.

If you are diligent in tracking and analyzing your errors, and work hard to correct them, you can do even better than you expected!

Hope this helps.

I also find that it's much easier to study the math. That one is pretty basic and it's mostly things you've learned before. However, I found that I used to more "tricks" to do well in the Verbal. Since I come from a family that doesn't speak a word of English, I found that these helped me more. I had taken a course so I'm in a different situation, but the books we used, I thought, were pretty good. They gave good tips for all sections, which mostly were very helpful. They're the Manhattan Review books (I think you can get them on Amazon?). Look into them if you have time. Either way, good luck!

I think gmat math is more about using tricks then trying to solve all the questions ?

If you have four weeks, I suggest you get cracking on those books. That is a lot of material to cover in 4 weeks. Ideally, you want to finish up all of your material with a week left to fine tune everything.

If you want extra practice in Math, you could try out a few of the Challenges on GMATClub. However, don't be disheartened by low scores as the questions are much harder than actual GMAT level questions.
