Hi there, I completed most of my first year online (aside from 4 weeks of in-person classes in trimester 1). For my Psychology courses, the exams were multiple choice in a set time frame that either was 1 minute per question or a bit longer than 1 minute per question. They made it that no student would get the same test (it was randomized from a large pool of questions) and there was no proctoring (to my knowledge) for the exams.
My other double degree is Law and instead of in-person final exams where we would have 2 hours to answer a problem question and an essay, they provided a take-home exam (similar to an assignment) in which we were given 72 hours to complete, also with a word limit to accommodate any technical difficulties and to manage around schedules.
Personally, I found that the psychology exams would mirror the in-person exams (since they would've been multiple-choice too) and would be roughly same amount of difficulty. However, for a course that involved statistics, there were no questions that involved the lengthier equations we were taught (as it was limited to be answered via multiple-choice) which I found a bit unfortunate. For law, I definitely feel underprepared for future in-person exams.
Although this is specific to my degrees, I hope this has helped provide some insight
