I'll second this. I am very familiar with latex. I have even done similar things to my neovim configuration (I use ultisnips) and have a few custom latex 'sty'les to include various commands to do stuff I do frequently but is a pain otherwise. This however is and was for end-product stuff: my own personal collection of condensed notes, assignments that needed to be typed, and so on (I also use ultisnips for coding). I studied mathematics as a undergrad (I have a first class degree in Mathematics from a UK university) and I hand-wrote my lectures, and I know many mathematicians that are frankly much better than I am who find computers frankly difficult and avoided LaTeX as long as they possibly could. What matters (if you are studying mathematics) is doing mathematics (exercises, experimentation, understanding proofs etc). There is no substitute. This is a nice to have, but will not make you a better mathematician. If you want to know how to be a good student, IMO this is a nice guide: https://www.maths.ox.ac.uk/system/files/attachments/study_public_0.pdf https://www.maths.ox.ac.uk/system/files/attachments/study_pu...
