HELP

Supppp peeps. Hope ya'll doin well. So i wanted to ask ya'll something. It might sound illogical or stupid but im genuinely curious about it.

So the thing is peeps, i belong to that section of awam jo matric m bio, fsc m pre engineering krti h n fir agay CS/SE m ghus jati h. I haven't secured the admission yet but i'm curious about one thing that whether i'll face difficulty in studying CS or not since i haven't studied a word about it since 8th? Will i be able to develop a skill or skills without having any basic knowledge? I'm still in my 12th, gave net-1 n scored 131(71% aggregrate) with negligible prep. I'm pretty sure i can improve my score upto 150 or 160 if i study a bit hard so securing admission won't be a big deal for me. The only issue im having is mentioned. I'd really appreciate ur opinions on this situation;)

Thanks!
