GENERAL RULES AND REGULATIONS FOR COMPLETING
CLINICAL GENETICS COURSE
This course comprises a series of tutorials, laboratory seminars and lectures. The
tutorials will mostly concentrate on genetic counselling in various clinical settings, the
laboratory seminars will feature presentations of laboratory methods and techniques used in
diagnosing genetic diseases. The lectures will introduce the basic concepts of mutagenesis and
molecular biology of cancer.
To pass the course it is necessary to attain a pass on the continuous assessment and to
attain a positive grade on the end-of-course examination. For the continuous assessment mark,
students will be assessed throughout the course, in the form of regular review by their course
tutors (that includes two written test). There will be an examination at the end of the semester
based upon the whole course. If a student should fail on the continuous assessment he/she will
be not allowed to sit the examination. The student will get a chance to write a final test based
on the tutorial and seminar material. Only then the student will be offered the opportunity to
take the examination.
Attendance at the tutorials and laboratory seminars is compulsory. Students can miss
one seminar or a tutorial without any repercussions. If the student misses more than one,
he/she should report to the Dean’s Office with an appropriate document stating the reasons of
absence. A copy should be presented to the tutor. There will be a chance to discuss the
omitted material at the end of the semester. Otherwise the student will fail on the continuous
assessment.
Students should prepare for each of the tutorials and laboratory seminars. The student
should be ready to discuss the clinical case and know the theory behind it.
