Nursing Maths

Hello.
I am currently TRYING 🫠 to pass my maths in order to start university in Sept.
I’ve been informed that. Maths Equivalency test may be available if I am not successful in passing Level 2 Functional Skills.
Has anyone done the equivalency test?
If so, can you tell me what it’s like and if it’s as horrendous as the level 2.
I’m fine at basic maths calculations but probability, area, algebra etc. my brain just says immediately no!
Thank you
