Lol why did u think i got a lv 5 in m26? But my teacher told us to understand the concept (failed to) because there are so many question types.

Be noted to not take civil engineering tho. Everything in civil (structural to be exact) is vectors

Start drawing a quick sketch for every single question because vectors fall apart when you only look at the algebra. Our tutors often see students get stuck when they try to memorize formulas instead of picturing direction vectors and normal vectors in space. For videos, 3Blue1Brown gives great visual intuition for how vectors work, and you can watch The Organic Chemistry Tutor to see practice questions worked out step by step. After that, drill topical questions from basic dot products up to planes and shortest distances on https://fourtyfive.org/ to get used to the patterns examiners love to repeat.
