Általános információk
1st academic year first semester
Lectures: 1.5 hours/week
Laboratory practices: 2.5 hours/week
Until otherwise stated the lectures and practices will be held online via zoom. The zoom meeting ID will be available at the given lecture or in moodle.
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. 13. 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:

The timetable of the Department can be downloaded here http://biofiz.semmelweis.hu/upload/file/orarend_2020_z.pdf
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.

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.
Rules of the online exam:
1. Only one device can be used for the exam. This device is preferably a computer or if it is not available, one tablet or one smartphone. It is your responsibility that the device has a suitable internet connection, video and audio input. In case of disconnecting from zoom during the exam, it is considered as the student did not attend.
2. The camera must be switched on during the whole exam. Headphones or earphones are not allowed for the students during the exam.
3. Sharing the desktop is obligatory during the whole exam. Sharing only a window instead of the desktop is not allowed. Besides the zoom application, only the formula collection found at the link below can be opened.
Only this pdf version of the formula collection is allowed, the printed version is forbidden.
4. Your face, chest, and hands must be visible on the camera during the whole exam.
5. You must only have a blank white paper and a pen in front of you during the exam. These should be shown to the camera at the beginning of the exam.
6. You must show your picture ID registered by the English Secretariat to the camera at the beginning of the exam.
"The form of the exam is an online zoom-meeting.
The exam is oral, you have to answer the questions without preparation time. You will get lab-related questions and theoretical questions. Beyond these, the examiners can ask further questions too.
The exams will be recorded and saved for 3 days.
On the day of the exam each examiner will create separate zoom meetings. On the morning of the exam day the students will be assigned randomly to the examiners. The assignments will be posted on our webpage to the documents, where the approximate starting time (Budapest local time), and the zoom meeting ID of the examiners will be presented for each Neptun code.
Consultations in the exam period will be on the following days at 3 p.m.:
Dec. 14, 21,28
Jan. 4, 11, 18, 25:
The zoom meeting ID will be given here before the consultation.
Zoom link for the consultation on Jan. 25:
