in Student Laboratory (Hallgatói Labor) of Chemistry Department (No. 8 at ground floor in bldg. C).

Evaluation description

Work in the Laboratory

1) Participation on each laboratory practical is compulsory and the attendance will be recorded each time. Students who are unable to take the laboratory exercise(s) are obliged to give a satisfactory oral review of the subject(s) missed during their excused absence (make-up lab). Students who missed more than three labs, have to re-take entire Veterinary and Food Chemistry course (with a new, unfilled Lab Manual) from February, 2020.*

For the make-up lab (Exercise 14) one should fill (copy and learn) all the missed lab(s) in the Manual and (s)he will be asked a few short questions from the missed lab. If they are properly answered then one can get the valid signature(s) for the missed lab(s). Note: the exam is not allowed with a missed lab exercise(s).

2) A thorough theoretical preparation is required to a successful laboratory work! Therefore, a precise study of the related section of the laboratory manual and the thematically relevant chapters of the lecture prior each laboratory exercise is a must. The preparedness of students can be checked at any time during the lab course and an unsatisfactory result will be considered as a missed lab exercise.

3) Wearing an apron (lab coat) and safety goggles is compulsory in the laboratory. At the first exercise every student has to choose a permanent place at one of the lab desks. The laboratory experiments should be done individually (except group-experiments). The observations, experimental data, and answers to the questions should be documented instantly in the Manual in the course of the laboratory exercises. However, it is highly advisable to write the reaction equations in the Manual prior the given lab (at home). The right-hand pages of the Manual are left for that purpose. At the end of the exercise the students have to clean the glass vessels and other tools and set back the reagents’ flasks of to their place. Before leaving the laboratory students have to get a valid signature in the Manual from the supervisor.

4) In order to help the students’ work consultations can be organized. Dates of the consultations will be announced later, as agreed with the students. The consultation is not a simple repetition of the given subject but it can assist to its better understanding.



1) Midterm Test

A midterm test (45 min.) should be written in the spring-term on


March 21, 7:15                      Chemistry of functional groups. (Hydrocarbons, oxo compounds). Lecture notes will be asked also! (20 points)

Students who missed the midterm test due to illness (the medical certificate must be shown to Dr. M. V. Pilipecz within 7 days after recovery) will have one chance to write make-up test on May 14, at 18:00. Further possibilities for the retake will be not given. The results of tests will be known for the students in 3 days from the writing date. Smartphones, graphic calculators, netbooks, tablets and other text storage electronic devices are not allowed to use during the tests/exams. Cheating, plagiarism or use the above mentioned devices are not tolerated (0 point), and the incidence will be promtly reported to Department of Student Affairs. The written test is evaluated on a 020 point scale and these points will be added to the final exam’s points.

* Since it has financial consequence therefore, please contact with Mr Péter Lessi at Department of Student Affairs.


Exam information

At the end of the spring-term the students have to write an end-of-term examination, which comprises all subjects of lectures and laboratory exercises of the spring-term. Duration of the exam is 120 minutes and it is evaluated on a 100 point grading system. The first part of the exam contains 10 short, fundamental questions. In case of less than 5 correct answers, the result of the exam is unsatisfactory, independently of the other parts of the exam. More information about the exam will be given in the lectures. In the exam there are no calculation exercises therefore only the use of an approved periodic table and ballpoint pen (with blue- or black ink) are allowed. Cheating or plagiarism in any form is not tolerated (0 point), and the incidence will be promtly reported to Department of Student Affairs.

The final grade of the terms will be determined by the sum of points from the midterm test and the Veterinary and Food Chemistry exam (20 + 100 = 120 points = 100 %), as follows:



                   0 – 59              (0 – 49 %)                   unsatisfactory (1)       

             60 – 74            (50 – 62 %)                 pass (2)                      

             75 – 89            (63 – 74 %)                 fair (3)                       

             90 – 104          (75 – 87 %)                 good (4)                     

105 – 120        (88 – 100 %)               excellent (5)


The Veterinary and Food Chemistry exams will be held on

May 22nd                                May 29th                     June 12nd                               June 26th

from 14:00 at Chemistry Lecture Hall. Please, be there 10 minutes before the exam at 13:50.
