Mastery exam: two mastery tests 1) 1-hour combined alpha & beta mastery test and 2) 45-min gamma mastery test (40% of final marks)

Coursework:
●  Item 1:Problem sheet Title:Alpha problem sheet Description: Weighting: 5 %
●  Item 2:Problem sheet Title:Beta problem sheet Description: Weighting: 5 %

Outline answers to past papers will be available

Exam rubric: One final exam consisting of 3 questions (1.5 hrs long, 50% of final marks) Two mastery tests: 1) 1-hour combined alpha & beta mastery test and 2) 45-min gamma mastery test

Feedback : The alpha and beta sub-courses will have 1 marked coursework activity. The coursework will be marked with feedback within 2 weeks (or less) in order to provide useful preparation for the mastery test. Similar activities will be worked on in the study groups. There will be two VLE based mastery test. The first mastery will be scheduled at the beginning of the spring term, and the second test will happen during the spring term. A mock mastery for each sub-course will be provided to assist preparation. Normal mastery test rubrics apply. The result will be revealed within 1 week of the assessment and will be revealed as Pass or Fail.
