How to study for the final

The final will cover all lecture and exercise-session material, with an emphasis on the topics covered after the midterm.

Here is a possible priority list for organizing your preparation:

1. If you did not follow lectures 7 (network layer), 8 (network layer, continued), and 10 (link layer), watch the corresponding pre-recorded lectures now. If you did, then review them (= go through the slides, flag the ones whose content you don't remember clearly, and watch the corresponding videos).
2. Do the basic questions from exercise sessions 9 and 11. The final always has a problem that involves IP prefix allocation + some end-systems exchange messages and you are asked to list the resulting packets (including ARP requests etc).
3. Do:
   final 2020, Problem 2, Questions 1 and 2; 
   final 2019, Problem 2, Questions 1 to 5.
4. Review lectures 5 (transport layer) and 6 (tcp). 
   
5. Do:
   final 2020, Problem 3, Question 1; 
   final 2019, Problem 4, Question 1.
6. If you did not follow lecture 9 (security), watch the corresponding pre-recorded lecture now. If you did follow it, then review it.
7. Do the basic questions from exercise session 10.
8. Review lectures 1 to 4.
9. Do:
   final 2020, Problem 1;
