In their own words:
I started tutoring because I kept noticing the same thing: most students who think they are “bad at math” are not. They missed one idea somewhere earlier, and everything built on top of it has felt shaky ever since. Find that gap, fix it properly, and the rest tends to move a lot faster than anyone expects.

I work through whatever class a student is actually taking — their textbook, their homework, the test coming up on Friday — rather than a generic curriculum. And I try to be the kind of person a student is willing to say “I still don’t get it” to, because that sentence is where the useful part of a session starts.

### Joining the team

We are actively recruiting instructors, particularly for advanced mathematics and physics, and for in-person teaching in areas we do not yet cover. Enquiries via https://alexplains.com/contact.
