Question

Please give me some tips and suggestions

Answer 1

Ok first Hi👋

I'm not a professional but these are what I found helpful in my learning journey (in fact still in the beginning).

-partical learning
learn bit by bit, (e.g10 minutes a day), focus in a concept,and take your time before diving in another concept.

-PRACTICE
Instantly solve problems in what you newly know.
if it's too easy take a challenge of harder one.

-revision
see past problems and try another way to solve.

-DON'T MEMERIZE!
after tring to solve remeber the general idea of solving a problem is ok, just don't go extreme and copy it without uderstanding.

But still this is my way you may have abetter one that fits you well.

Book:
Schums outline of calculus(z-libraries)

I will add relative algebra book if i find a good one.

Hope i didn't talk too much🙃.
