I need help with pretty much all topics..

[sharp hamlet]

honestly we cant help u with "everything" here, since there are too much of them to cover
i think it should be better to find a personal tutor or seek help from school teachers
if u could specify or focus on a topic/concept/question u have, i think we may be able to help u more

khanacademy, maybe?

you have about a month or so to go through stuff on there

that way you can find out what you struggle with more and what you struggle with less and then come here for more specific stuff
