- Take some mock tests in between your preparation schedule.
- Do not try to improve it one by one.
- Try to work on all the sections evenly so that you remember the shortcuts/strategies whatever you learn till the end.
- Two whole months of preparation without any mock tests in the middle will not be of much use.
- You should know where you stand and how much you need to improve, what you need to learn in order to reach that score - All these can be done only with the help of mock tests.
- A whole month for IR and AWA is a total waste of time - you should spend a day or two for those or may be a week at the max.

The purpose of the mock tests is to
* improve your timing strategy
* testing experience
* analyze where you are weak and where you are strong

You wont gain anything taking loads of tests in the last month alone.
