I have scored 660 on GMATprep with 47q 35v.

I am not yet confident with math as I feel that I lack some knowledge of probability and combinatorics though I have done Mgmat Word Translation twice.

Shall I start doing GMATclub tests or is it better to completely revise official guide and quant review so that I know every question in and out?

Both of those sections are advanced math questions on the GMAT and some people report never seeing a combinatorics problem on the GMAT.

If you lack concept understanding, I would work through some content before crashing through problem sets.

Walker posted a guide on combinatrorics and probability:
math-combinatorics-87345.html
math-probability-87244.html

There are also a number of brutal problem sets in the math forum (look for Bunuel threads with questions).

You need 1 point in math and 3 points in verbal to get to the 80+ percentile in both sections. You're very close.

Mohater, thank you for the exhaustive answer. The guides you proposed are really great at glance, I shall certainly study them. The inspiration is great too!

Well, Whiplash proposed a method of study which I feel is the best way to improve upon a specific topic. The system is as follows:
1. Familiarity -
The aim here is conceptual clarity. Learn all the formula and theory involved in a particular topic.

2. Strategy -
Once you're familiar with the concepts, you can start solving problems from various sources to apply the concepts learned in the previous step. The aim here is to improve the accuracy by understanding each and every step that leads to the answer and by finding novel approaches to solve similar types of problems more efficiently. Speed can wait.

3. Practice -
In this stage, the main aim is to work on timing. See if you're able to solve problems under two minutes.

4. Test -
Check if you've reached the stage of proficiency you desired.

I hope this helps...

NOTE:
I gave my GMAT yesterday and I had just one question from Permutation and Combination.
Overall, the topic wise distribution of questions was even. However, questions from Numbers, Geometry, Inequalities and Modulus, and speed-time-distance were more frequent.

Regards,
Entwistle
