Well okay, I did better than I thought. Though I got the answer to the k mass wrong. I got 13 somehow. I got the inequality with e wrong and I also got the magnitude of the reaction wrong. So worst case scenario meaning I got no method marks, I got 61/75. Honestly coming out of that exam I felt sick and I thought I genuinely got like 30% due to how my answers were weird.
For that vertical question, I think I must apologise to my examiner since I got a little angry, underlined the word vertical, stated that it was always ninety degrees from the horizontal and that the question is wrong. Honestly that question was stupid. I got the answer wrong sure, but probably due to my rage at the wording.
The last one was really weird but I came out with 2.5 which is a relief. I did some strange z-angle thing, lol.
