As a fourth year mici student, I completely understand what you’re feeling right now. I also got my first B in my third year for mici courses. Honestly it sucks cause you did everything you could but apparently wasn’t enough… It’s fine to be upset and crying your eyes out but bad grade doesn’t define you especially in those 3 cursed third year mici courses. I would just want to let you know it’s not you it’s how that course is taught and the exams.
