Autonomy and responsibilities

Requirements, evaluation and grading
Mid-term study requirements

2 midterm tests will be written at the practical lessons. There will be at least 50-50 points reachable for each. Summarized 50pts are enough to fulfill the requirements for signature. Over 80 pts mark 4, over 90 pts mark 5 will be offered. Improving your result and/or fill tests are possible at the end of study period, but improving only for signature.

Exam requirements

The exams are divided into test and oral part. Test should be written above 50% let you to take oral part of the exam. Oral part means questions about your test work and one short presentation about one of the magnetic topics given earlier.

Generative AI usage

Use of GAI tools is not permitted for solving assignments. This means GAI tools cannot be used to complete formative or summative assessments, and using GAI constitutes academic misconduct. The use of AI tools for spelling and grammar checking does not fall under this prohibition.
