Connected items: You are presented with two lists of items, and you have to find the items in list 2, which fit to those in list 1. Note that an item in List 2 may belong to several items in list 1.

In addition, some essay type questions and some questions were a short answer needs to be filled in were also presented. Such questions are used to test understanding and problem solving, rather than memorysation. Thus for merely repeating the material given in the lecture you will not receive full marks.

Some hints about exams

Be on time, and bring all required materials with you. It should not be necessary to say that, but experience shows that it is. You will be told in advance which materials are required/allowed in the exam, make sure you completely understand that.

In many exams, you will be supplied with enough paper to write your answers and to make any intermediate calculations. In such cases, you must not use any other paper than that supplied, and you must return all sheets provided, even if they are empty. Failure to obey either rule will count as cheating.

Read the exam completely before you start. Make sure that you understand exactly what is asked of you. Do you have to answer all questions, or do you have to choose some? In the latter case, you will not be given extra points for answering more questions than you were asked to do, so don't waste your time.

Read each question carefully, including all possible answers before choosing one of them. Remember also that in a biochemistry exam you will not be expected to do complicated maths. Numbers will usually be chosen so that calculations — if required at all — can be done in the head, without calculator. So if a calculation gets complicated, you are probably on the wrong track.

The problem with multiple choice exams (from the point of view of the examiner) is that students have a chance of 20 % to find the correct answer by guessing. Thus in some exams negative points are given for wrong answers. If negative points are not given, it is to your advantage to mark any answer if you do not know the correct one (since, statistically, you will get 0.2 points for it). However, if negative points are given, guessing will on average lead to a loss of points (4 possibilities for —1 and one possibility for +1 point, so the average will be —0.6 points). Under these conditions it is best to leave the answer open (0 points), unless you have a strong guess.

Even in those places where wrong and missing answers are both given 0 points, examiners have developed ways to guide non-knowing students to the wrong answers. Experience shows for example that guessing students will preferentially choose between two mutually exclusive options, even if both are wrong. There will be some examples for this type of questions below.
