Weekly graded assignment deadlines are published on the course portal once the term starts; each course's week pages here show them when they are announced.
Before week 1
- Finish your application before it closes and keep the payment receipt.
- Know your four courses. Open your programme page — Data Science or Electronic Systems — and skim the week 1 topics of each course.
- Understand the hall-ticket rule now, not after week 3: your best two of the first three graded assignments in every course decide whether you can sit the exam.
During the four weeks
Each week follows the same rhythm: watch the lectures, try the practice and activity questions, then submit the graded assignment before its deadline. Treat weeks 1 and 2 as the attempts that count and keep week 3 as your safety net. The GA calculator shows where you stand after each week.
Before the exam
The exam covers weeks 1–4 of every course. From week 4, revise with each course's formula sheet and exam-prep page, and check the pass marks so you know the score you need in your weakest course.
