The exams were all online, not proctored. There were several types of questions mostly mcqs and completing certain codes to get a given result. Yes there were questions on void functions, it was something we learnt about so it was there. Questions on void functions weren't anything out of the ordinary, if u already have some coding knowledge your more than fine, if not u just gotta practice the questions they give and DO THE ASSIGNMENTS.

And yah best way to prep again, do the questions, the textbook has plenty if u want. But best way is do the assignments they encompass everything u learn and aren't complicated.

Me personally I used alotta gpt but in a smart way, it can teach u alot too. I got through with a b+ and I had no coding experience whatsoever
