Where can I find some free Algebra 2 lessons and problems?

I am going into Algebra 2 next year and I was wondering if there was a website, youtube series or something of the sorts I could use that has some Algebra 2 lessons and the coordinating problems. I want to run through some lessons to get a grasp of what it is going to be like next year and get a head start so they will still be fresh in my memory by the time school starts.

If there are any math help subreddits and I posted this in the wrong place, sorry about that, and please link me to them.

(Also, if there are any exceptional storebought workbooks that you know of please provide info on those as well, however internet resources are preferred.)
