SF Mathematics & Theoretical Physics, JS & SS Two-subject Moderatorship
The format will be the same as in the year 2010/2011 exam,
which can be considered a sample paper.
Credit will be given for the best 4 questions out of total 5 questions.
The theoretical questions will be within the scope of the current course
and the practical problems within the scope of the current homework.
The exam will count for 100% of the grade.
