Is this site suitable for closing gaps in a school algebra course?

Question

Mathematics

Gentlemen, who is not lazy, take a quick look at this site and tell me if this is a normal site to close class problems like that from 8? Or at least close the gaps in order to switch to Scanavi normally, it is still difficult.

Answer 1

I don’t know about Scanavi, but the site is decent. I can even help myself if something is not clear
