How to learn Figma?

Hello everyone,

I know the title is very oversimplified and the answer is very obvious.

What I'm actually asking is this:
1. are there any good tutorials on youtube or other platforms that will explain the basics and the inteface?
2. is there a good course I could purchase or sth similar?

The thing is, I'm a PM and I have always been interested in design but never really used any tools except for Canva (I know it's shamed upon by actual designers). Now my gf has to do a course at her faculty with Figma and I want to help her but also take it as an opportunity to learn it myself.

I have given myself a time period of 7 days (3-4 hours per day) to learn as much as possible. Mind you, I already know quite a bit about the fundamentals and principles of design itself.

I have actually already been learning Figma, but it's never a sin to ask if anyone has some really good recommendations or resources that would make my process easier or speed it up.

Thank you!

Luka
