2 Important Information The solutions provided in the correction guide can only be awarded the points indicated. The score must in each case be a whole number. If the examinee fails to answer as set out in the instructions, the answer will not be accepted. (E.g.: Instead of the letter F, the examinee cannot answer with the letter N.) If the question calls for a single answer (e.g. a single letter), and the examinee provides several different solutions (e.g. several different letters), then no points may be awarded. If a question calls for a single answer, as stated in the instructions, the points awardable cannot be broken down, e.g. in the case of a 2-point question, only 0 or 2 points may be awarded. In such cases, the correction guide provides detailed information on how partial points should be awarded. If the examinee has made corrections or revised the solution, but this correction is not clear, then the answer may not be accepted and 0 points must be given. In case of clear corrections, the corrected solution must be evaluated. If, due to the use of a system that differs from the usual, the examinee has provided an answer other than the one expected, but the solution and subsequent explanation is acceptable, the points awardable for the question must be awarded. írásbeli vizsga / május 19.
