I started integral calculus . after it what topics should i prepare tell me one by one(the order)

ode ,topology in real no.'s, seq series, differential calculus, group theory, linear Algebra. (or you can decide by youself according to interest)

if you have completed integral calculus completely, you can start differential equations

you should do ode then vector, real analysis ( include everything like limit, continuity, differentiability max. Min. of all variables and so on). sequence and series, group the...
