Submitting your assignments

All the assignments must be solved using the following PDF template. The assignments must be delivered to the teacher at the beginning of the problem solving sessions. No submission by email is possible. Please, note that each assignment has been assigned a code (for example M1.1). You will have to include this code in the template. The deadline for each assignment will be published within the Tentative Schedule section. All the deadlines are firm, so NO extensions will be given.
