The following rules should hold:

1) students should bring exam sheets and solve each question (max. 6) in a separate sheet of paper.

2) students may only consult an A4 sheet of paper with formulas. This sheet is prepared by the student. 

3) Calculators with an alphanumeric keyboard (i.e., with a computer-like keyboard, with individual keys for each of the letters of the alphabet) are not allowed.  Use of phones or of any other communication equipment is not allowed, even for use as calculators or as clocks.
