1st academic year first semester
Lectures: 1.5 hours/week
Laboratory practices: 2.5 hours/week
Credit: 4 (for one semester)
Tutor: Dr. István Voszka (phone: 4591500 ext: 60234)
Exemption:
If one wants to get exemption from the subject based on the previous studies must give the application to the tutor until Sept. 10. The transcript (original or validated copy) and the detailed topic list of the relevant subjects should be attached. If there is a proper overlap between the topics (at least 75%) we check the knowledge of applicants by a written test containing multiple choice questions at the beginning of the second week of the semester.
The attached sample test shows the style of questions. The real test will contain 40 questions.

Lectures: The participation is strongly suggested. The explanations and mathematical descriptions given on the lectures help to understand the material. Without understanding the preparation to the exam is very difficult and in many cases not successful. According to the rules the participation on the lectures will not be checked.
Laboratory practices.Students have to prepare for the laboratory practices by reading the corresponding chapter of the Laboratory Manual. Based on this one can ask questions for better understanding. One has to make lab. report about the measurements.
The order of laboratory practices can be found here:

Rules for lab reports :
1. Every lab report is considered as a written test, where three types of grades can be given: „Accepted” „Correction needed” or „Not accepted” .
2. The lab. report should be done by filling the excel sheet downloaded from the homepage of the department.
3. The processing of data can be accepted only if it is based on the data measured by the student.
4. Only the tasks listed in the homepage are required for a certain measurement. The lab report must be uploaded during the lab.
5. The teacher will show, what is the mistake or missing part in the lab report.
The practical grade is given based on the followings:
- grade of 3 tests during the semester (after each measurement cycle 5 questions written test in 30 minutes). In case of absence it can be done orally at the teacher of the group.
- evaluation of lab. reports. (If one has more than 3 "Not accepted" lab. reports, the signature is denied.)
- quality of work on the laboratory practices.
Missed measurements
Participation in the practical lessons is compulsory. No more than three absences from practices are allowed for any reason, otherwise the semester will not be credited. The missed measurements should be done with another group during the 4 weeks cycle of laboratory practices if possible. (One should ask for the agreement of the teacher of own group and the other group.)
Conditions for signature:
1. At least 50 points in the test in Physical bases of biophysics.
2. Participation on at least 75 % of the practices, (in case of more than 3 absences the signature for the semester is denied.)
3. The practice grade should be at least 2.
In very special cases of more than 3 absences just the head of the Department can make a decision about the exceptional signature.
Exams
The exam is oral. The students get questions generated randomly both from laboratory practices and theory.
Formula collection can be used on the exams. It can be downloaded here:

We call the attention that we do not give permission to take Biophysics II. without passing Biophysics I.
A tantárgy rövid leírása
Biophysics plays a basic role in the education of pharmaceutical students. There are dual role of the subject: on one side it gives general knowledge of natural sciences, on the other side it gives theoretical and practical basis of application of physical principles and methods in pharmaceutical sciences.
In connection to this it helps the development of structured way of thinking. Through this one can find connection to the basic subjects and to the applied pharmaceutical subjects.

The third test in biophxsics will be on December 3rd (Friday) at 5 p.m. in the student laboratories of the department. One can use calculator, paper and pen or pencil during the test. We give the formula collection. The answers have to be given in the moodle system. The material of the test is the material of lectures between Sept. 6. and Nov. 26. and laboratory practices between Sept. 6. and Nov. 12.
Everybody should bring ID card to the exam. In the absence of ID card the exam can not be started.. We call your attention, that during the midterm tests and exams one can use calculator with max. 2 lines display only.
One must pass two from the three tests. So the students, who passed both tests, do not have to write the third one. The students, who failed both the first and second test will get 2 s the practice grade if they pass the third test.
Consultations in the exam period will be on the following days at 3 p.m. online via zoom (the actual zoom link will be on the homepage a few days before the consultation):
December 13, 20, 27
January 3, 10, 17, 24
On Jan. 24. one can join to the consultation via the following link:

Requests for the exam outside exam period should be sent to Dr. István Voszka
