If the course is discontinued, students may request to be examined during the following two academic years.

A, B, C, D, E, FX, F

- TEN1 - Examination, 2.0 credits, Grading scale: A, B, C, D, E, FX, F
- TEN2 - Examination, 2.0 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Written or oral examination and/or home assignments.
