Any resources or websites from basic math to advanced math up to calculus 2?

It normally takes some period of years to learn all math and you have to use it at least occasionally or you forget large parts.

It is hard to believe that you need to brush up on all math. Any actual project does not need all aspects at the same time. For instance, geometry is only rarely needed. Trigonometry is based on principles such that if you ever learned them, you can derive whatever you need when you need it.

If you never learned basic math, you are not likely to learn any advanced topics now.

But assuming you need what you say, go to the community college and buy the books.
