Basic mathematical help or tips

Hello! 

Du kan absolut svara på svenska. Jag föredrar att förklara något som jag bör berätta i detaljer på engelska. 

I have some majors in my mind that I’d like to apply for. But the thing is that I need mathematics 2b/c and 3b/c. It has been nearly 10 years since I studied mathematics and it has made me begin with ABC. I am most likely to get a private teacher to get some help. However I’d like to study something by myself as basic math doesn’t require sophisticated skills. Plus there are a lot of resources out there. So, I’d like to get some tips which textbooks I can buy to study math that applies to Svenska NP för mate. 

Thank you so much.
