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, 2021.*

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.

 

Requirements

1) Midterm Test

A midterm test will be written in the spring-term on

 

April 21, 700 – 800        Organic chemistry. (Lecture notes and also lab topics)

Everyone who reaches in this midterm test at least 70% gets exemption from the written part of the exam at the end of the term with an excellent (5) grade. 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 promptly reported to Department of Student Affairs.

 

2) Examination

The exam of the course consists of a written and an oral part. Students have 30 minutes to complete the written part consisting simple-choice questions which  cover all subjects of lectures and laboratory exercises of the spring-term.

The grade of the written part will be determined by the sum of the points from simple-choice questions on the five-scaled Hungarian grading system as follows:

 

0 – 49 %                                 unsatisfactory (1)      

                                   50 – 62 %                               pass (2)                      

                                    63 – 74 %                               fair (3)                                   

                                    75 – 87 %                               good (4)                     

                                   88 – 100 %                             excellent (5)

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 (unsatisfactory), and the incidence will be promptly reported to Department of Student Affairs.

Students who have less than 50 % result are not permitted to continue the exam and its grade (failed) will be introduced in the lecture book.

 

In the oral exam, every student has to answer orally two short topics from different parts of organic  and food chemistry. We provide 10 minutes for preparation and to make a sketch about the topics

The final grade will be calculated from the results of the two exam parts, but if any part of the exam is unsatisfactory, the final result will also be insufficient.

 

The topics of the oral exam and the exam dates will be announced in time. The Veterinary and Food Chemistry exams will start at 8:00 in Chemistry Lecture Hall.

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