GMAT Club Tests Quant Review

GMAT Club test questions, specially the 700+ quant questions, were by far the best study material I used. Key areas where i learnt new tricks were below:
1. Consecutive integers and squares properties
2. Rate/Motion question types
3. Inequalities and Absolute values
4. Nested geometry figures
5. Combinatorics and Probaility
6. Coordinate Geometry

I practiced all questions in Quiz mode personally to improve on topic wise timing and tricks. The strategy I would recommend would be the following:
1. Take practice test 1
2. Identify your strong and week points and log them in the error log
3. Curate custom quizzes on both strong and weak areas.
4. On Strong areas focus on improving accuracy and timing
5. On weak areas focus on learning the material so initially take as much time as you need to get the problem right. Repeat process to focus on timing
5. ALWAYS read Bunuel's solution techniques even on questions you got right because he will teach you the tricks to solve the questions faster.
