Form(s) of Assessment (additional text)

The exam consists of two main parts. The main parts are divided into sub-parts, these include the final exam of CCNA R&S Module 1 + 2, a written subnetting exercise, a router configuration part using Packet Tracer simulation software and a written exam of network security.
Part 1:  - electronic chapter exam (11 points) and final exam (39 points) CCNA Module 1
- written exam subnetting (25 points)
- skill test Packet Tracer (25 points),
counts 1/2 of final grade
Part 2: - electronic chapter exam (11 points) and final exam (39 points) CCNA Module 2
- written exam network security (50 points),
counts 1/2 of final grade
All sub-parts must be passed to pass the course
An overall evaluation based on a 200 point scale, where the first exam counts 100 points, the second exam counts 100. In order to pass the course both exams and sub-exams have to be passed (i.e. at least 35% score).
Conversion from 200 point scale to A-F scale according to recommended conversion table. In specific circumstances, emneansvarlig can slightly adjust the limits in the conversion table to enforce compatibility with the qualitative descriptions on the A-F scale.
