Please, I need help

So these are my grades throughout highschool, and I'm trying to catch up for personal reasons. I'm currently doing night school for prerequisite course so I'll be able to take that for next semester. Thing is I've been studying, and trying different techniques but idk, it just don't work. Right now, I got a 52 in ENG4U1, 40 in PSK4U1, 77 in HSE4M1, & 60 in SB13U1, ended up dropping MDM4U1 because of issues with the teacher. I've spoke with my guidance counselor on some of my failing in particular to been in hospital for sickness throughout high school. I've also not applied to university yet, (guidance say I have a duration till when). Id also still be able to graduate since ill have 30 credits, but will have to take SCH4U1 in summer. I'd like to get into a nursing program which I heard is competitive and I need the marks for. PLEASE, Please any advice that I can do for further improvements on my grades before winter break hits.
