The first thing to do is figure out why you got certain questions wrong. Have you thoroughly reviewed the answer explanations?

This might help :

- Learn SC Rules
- Practise GMAT questions
- Analyze each question and find out "What is being tested ?"
- Almost all questions in GMAT have 3:2 split. You can figure that out with practice. This split will improve your speed. You can straight away eliminate 2/3 options in just 10-15 secs.
- Learn about the question types
- More than everything, just practise.

First concentrate on concepts. When you are sure about them, try concentrating on speed !

I am not an expert but this is what I have heard from the ones in 700+ GMAT club.

Look at questions in each area and really study the differences in question. Both in what is tested and how right and wrong answers are presented. Look at the OG to start.
