Documented knowledge in English, for example upper secondary course Eng B/6. Or English 6 in an internationally recognised English language test, for example an IELTS Academic/IELTS UKVI total points of 6.5 and no section below 5.5.

Special admission requirements are also fulfilled through Swedish or foreign education, practical experience or due to other circumstances is in a position to benefit from the education. Regulation 2018:1503, section 5b.

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

• INL1 - Assignment, 3.0 credits, grading scale: P, F
• INL2 - Assignment, 1.5 credits, grading scale: P, F
• INL3 - Assignment, 1.5 credits, grading scale: P, F
• TEN1 - Oral examination, - 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.
