I try to all my tasks as soon as possible in November because than I can focus for 100% on the exams. 

I learn according to the exam schedule, for example; Spanish is 2 days after economics that's why I am going to learn everything beforehand.

But between law and French there are 9 days, so I study for economics and Spanish the first days after law but focus 4 full days on French.

The key is to summarize and learn everything during the year/before the exam period.
