Exemption
If one wants to get an exemption from the subject based on the previous studies must give the application to the tutor until Sept. 9. 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.
Laboratory practices
Students have to prepare for the laboratory practices by reading the corresponding chapter of the Laboratory Manual
The form for the lab report that can be used in case of error in the network can be downloaded here:
The schedule of laboratory practices can be found here:
http://biofiz.semmelweis.hu/upload/file/gyakre_2022z.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.
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.)
The timetable of the Department can be downloaded here:
http://biofiz.semmelweis.hu/upload/file/orarend_2022z.pdf
Students must write a lab. report for each measurement in excel. The file to be filled can be downloaded from the homepage of the Department. The students should prepare for the measurement by reading the related chapter of the laboratory manual.
In case if one has more than three “Not accepted” lab reports the signature for the semester is denied.
Conditions for signature
1. At least 50 points in the test in Mathematical and physical bases of medical 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. Acceptance of the lab. reports. If one has more than 3 „not accepted” lab. reports, the signature is denied. The lab reports must be uploaded to the website at the end of the practice.
In very special cases of more than 3 absences, just the head of the Department can make a decision about the exceptional signature.
Midterm test
-
There will be one midterm test during the semester
-
It will be in the form of moodle test during the laboratory practice
-
Tasks: Calculations, similar to those among the exam questions, analysis of diagram, theoretical questions related to laboratory practices
-
Material: laboratory practices between the first and tenth weeks + calculations
-
Date: biophysics practice on the 11th week (between Nov. 14 and 18)
-
Students can use Formula collection and calculator during the test.
-
Favours:
-
Faculty of Medicine: The students achieving at least 60 % of points will get exemption from the calculation question on the exam. Students achieving at least 85 % of points will get exemption from the first three questions of the exam (calculation, evaluation of data from measurement, and practice question)
-
If one achieves favour it does not mean grade 5 for the exempted question and does not mean successful exam in any case just the exam will be simplified.
-
In case of unsuccessful exam the favour is lost and on the retake all the questions must be answered.
-
The midterm test can not be repeated or taken later, it can be written only with the student’s own group during the practice.
-
If one wants to check the test it will be possible during the 12th week in the presence of lab. teacher.
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: Formula Collection
We call the attention that we do not give permission to take Medical biophysics II. without passing Medical biophysics I.
A tantárgy feladata az orvosképzés céljainak megvalósításában
Our teaching program is evolving continuously. Focused on the general objective of meeting the requirements of the medical curriculum, the courses are also intended to provide specific medical biophysics training.
Today's students will be the physicians of the oncoming decades. In selecting and highlighting topics of study, the first viewpoint is scientific foresight: the knowledge should be conveyed which must be pertinent to ensure first-class professional competence while keeping abreast of the most recent development in the field of study. Our aim is not only the teaching of a specific body of knowledge but also the development of the exact scientific method and concrete problem-solving abilities.

Everybody should prepare an ID card to the exam. In the absence of ID card the exam can not be started. We call your attention, that during the exams calculator with max. 2 lines display only.
We call your attention, that there is no possibility to increase the number of exam days or places during the exam period, since we teach students on 3 faculties and 3 languages.
