Desperate to get a first - help!

I'm currently in my final year at MMU, studying Linguistics with French.

In first year, I got 92 overall, and 72 in second year (second year was rough, girl!)

I'm ADAMENT to get a first. After the A Levels disaster of 2020 causing me to not get my first choice, I really want to prove myself. The catch? I'm worried to start any of my work in case I flop.

My teachers are super supportive and have already said that they want to help me in any and all ways. My favourite teacher, however, is so worried - he's seen people dying for a first, only to not receive what they want and they crumble.

HELP!
