If you reckon you're 'prepped' and have jumped through the hoops that the CAA place on the system then go for it. Why you need months between the exams when you think you're ready is anyone's guess.
I did all the exams I needed in a single sitting and it wasn't stressful in the slightest.
Enjoy.
Don't bother with the coffee machine on the ground floor, get the good, subsidised stuff from the canteen on the top floor.
