Teaching and Learning Strategies

Teaching method: Laboratory Work
Description:
Laboratory work will be used to illustrate theoretical concepts and develop practical skills.
The part of the laboratory work forms the basis of the practical examination.

Teaching Method: Lecture
Description:
Lectures will be used to introduce new topics, identify the scope of each topic, highlight key points within it and explain the more complex or difficult parts and, where necessary, resolve conflicts that you might encounter in textbooks.
