one month to tackle the 14 exams???
Not if you're human, even if you're an experienced pilot! Schools usually split the exams through 3 sittings. I'd put them in groups of similarity like:
-Performance with Principle of flight
-Planning with Navigation
-Air Law with operational procedures
-etc.
Now,
0. Go to class, if you can't go straight to n.1
1. Read the books
2. Read them again and this time take notes
3. Buy Bristol database to help you actually pass the exams. Study at least 2 months ahead of each sitting. Do the whole database of a particular subject and THEN do the mocks and
write down your results to evaluate your progress. (I even took notes of the areas I was consistently failing and went bak to the books sometimes.
4. During the mocks write down the questions and answers you keep failing. (When you go to bed before sleep read them).
5. Aim for +90% on mocks within a week before the exams. The pressure and different question structuring will make you lower your results by 10%.
Note: If for instance you're tackling 4 subjects, during the 2 months study , regularly take mocks on all of them. DO NOT leave a subject "unattended" for more than a week or you might regret it.
I know for a fact that passing the ATPL exams has been more and more difficult in the last few years here not sure how is it like in the UK though
Hope it helps.
