This yielded for each student a number of points n_i for each problem i and a sum N=∑_i?n_i. The maximum number of points m_i for each problem i gives the maximum score M=∑_i?m_i. The following maximum points were as indicated in the exam text. Problem 1: a)2, b)1, c)2, d)1, e)3, f)4, g)3. Problem 2: a)3, b)2, c)1, d)3, e)1. Problem 3: a)4, b)1, c)1, d)1, e)5.
