Instructions for marking intermediate level papers 1. Always use red ink. 2. Tick the correct answers. Each tick is awarded. Half points cannot be given. Put two ticks if the candidate answered a question with 2 points correctly. 3. If the answer is correct but not included in the marking scheme it can still be accepted. The same principle applies to synonims. (e. g. :platelets trombocytes) 4. Equally correct, alternative ansewers are separated with a backslash (/) in the marking scheme. 5. At the end of each task add up the points in the grey chart. 6. At the end of the paper indicate the total points awarded for each task in the final summary chart and, by adding them up, work out the total score. 7. The total score achieved in the paper has to be multiplied by 1.25 to give the total score in percentages for the written part of the examination. 8. If the calculated total score is not an integer it has to be rounded according to the rules of rounding. 9. If the candidate is asked to compose whole sentences (e.g. to give reasons or explanations) only grammatically correct sentences can be accepted. Please, do not deduct points for spelling mistakes but do not accept answers with ambigious meaning. Good luck for your work. írásbeli vizsga 1121 2 / 6 2014. május 14.
