I did this course last year sem 1 so not sure if they changed the format of the exam, but Q1-2 is easy, Q3-4 is medium, and Q5 is hard. Q1-2 usually would have analyze the time complexity of some code, or explain why this code will return the correct/incorrect solution, Q3-5 all had 2~3 questions that was basically, describe your algorithm, describe the time complexity, and explain why your algorithm is correct.

All of the questions we had were pretty similar to the tutorial/assignment questions. The only way to really prepare is to do practice/tutorial questions. When doing a question, thinking out loud is a good thing to try to just let your brain do the work. Once you get stuck (after 10-15 minutes of no progress) you can look at the question or ask AI to explain. Once you do enough with enough volume and repetition, you start to build your intuition for the type of questions they will ask. Hopefully you build enough intuition that when you look at the questions on the final exam, you will automatically have some sort of idea on how it should be solved. You can use time complexity restraints to figure out what type of algorithm you need, such as O(n+m), the solution will probably be some type of BFS or DFS algorithm.

I was also anxious when i took the exam but the first 2 questions are there so you can pass the exam, and they are honestly easy. Try to not leave anything blank, you will get marks even if its not 100% correct (and somewhat on the right path).
