Assessment
Assessment strategy
Referral Method
By examination, the final mark will be calculated both with and without the coursework assessment mark carried forward, and the higher result taken
Summative
This is how we’ll formally assess what you have learned in this module.
Method | Percentage contribution |
---|---|
In-class Test | 25% |
Laboratory | 39% |
Problem Sheets | 36% |
Referral
This is how we’ll assess you if you don’t meet the criteria to pass this module.
