The final grade is 50-50% based on the laboratory practice reports and the written exam.

Laboratory practice reports (50% of the final grade):

• Everyone should perform 7 laboratory experiments, based on the weekly schedule above.
• A written laboratory report about each of the practices performed should be submitted at the end of the semester to the instructors (Dr. András Kiss or Dr. Gábor Lente).
• Everyone must submit their own report individually, even if the measurements were performed in 3- or 4-membered working groups.
• Submission deadline: ???11 December 2024???.
• The laboratory reports will be corrected and handed back to everyone.
• Return date: ???18 December 2024???.

Written exam (50% of the final grade):

• Dates are announced in NEPTUN. You must register in NEPTUN for the selected date.
• Types of question on the written exam:
  1. multiple choice questions (based on the lecture material),
  2. short essays, basic equations, definitions, and diagrams (based on the lecture material),
  3. false or true questions (based on the lecture material),
  4. calculations (based on the laboratory practice).
