I am trying to re-learn math as a 28 year old. Apparently these are the books that are recommended for these topics for olympiad guys and guys preparing for entrance exams for top unis here. These old books and as with any old books there are probably a lot of modern alternatives.

S.L Loney's

The Elements of Coordinate Geometry Part I
The Elements of Coordinate Geometry Part II
Statics and Dynamics Part I
Statics and Dynamics Part II
Plane Trigonometry Part 1

I plan on using apostol and spivak for calculus and those are good right?(after doing some online courses)
