I collected as many books as I can but now the problem is how can I set a curriculum for myself.

>Background

I'm a Third Year Computer Science student who has always struggled with maths, as a result, I barely passed every maths course that was in my curriculum.

Now it's been haunting me and now I want to sort of redeem myself in Mathematics where I felt short, my plan is to pursue a online Maths degree while I work full time as a Software Developer.

Can /sci/ please help me sort out where to start with pic related subjects? I appreciate the help thank you.
