Some corrections and last advice for the exam

Some corrections:

• I have rewritten the explanation for the use of the martingale method to solve the optimization problem in problem 3 (last year's exam) and exercise 7 (List 4).
• I have explained better the solution to Problem 1. 3. a) in the compulsory assignment.

In order to prepare for the exam:

• Check that you are studying from the last updates of lectures, exercises, etc...
• Have a look at the last year's exam to have a good idea of what kind of questions to expect in the exam.
• I remind you that no calculator is allowed in the exam. You can write the answer to the problems, when needed, in terms of fractions, logarithms, roots, etc...  

Best luck to everyone!!!
