If you're like me and you have no humanities subjects, or you're doing 'The Asian 5', then I suggest you do this:

- Read through the Mathematics questions thoroughly in the reading time.

- Complete all Maths questions first. If you are a strong student this shouldn't take more than 30-45 minutes.

- Return to the essays at the front. You should have just over 2 hours to left. Split that into an hour for each essay.

- Make sure to write expository/informative type essays without retelling the given information.

- In the last 5 minutes, go back to the multiple choice and fluke the remaining questions.

GAT complete. I did this last year, finished the GAT in under an hour and a half (couldn't be bothered with essays) and got 31/35 for the maths section. Break a leg end of year.
