[O levels] usage of computers in jc(?)

hi idk what tag to use for this hopefully the jc students can see, but btw if u do see this thank for taking the time to read this because i think now it’s y’all a levels(?) but anyway imma get straight to the point

so like let’s just say i don’t have a computer to use for jc, but like let’s say i have an ipad pro with the keyboard and google docs all, can i use this for jc? or is a computer like really necessary because i don’t want to purchase a separate computer for studies and if i do i would use a long lasting one like mac (like no opposition against windows but ya)

would be great if you could tell me what school you’re from or even if you’re not in jc you can leave your suggestions and opinions below, and once again thank you for taking the time to read all the best for y’all exams!!
