So after finishing calculus 1 and 2 I dropped out of uni for about a year and now I am returning in september and I have a 2nd year course in probability and statistics lined up that has calc 2 as a prerequisite. I am fairly confident I forgot most material on integral calculus and I don't know just how much I have forgotten from differential calculus. I want to take a course on calculus to refresh my knowledge so I am prepared for september.

Can anyone recommend me something from Udemy, Coursera, or a similar platform that you have done that helped you? And please do not recommend any super advanced Analysis texts by Russian Jews. I am trying to get a refresher on first year undergrad math, not become the next John Nash.

I have a little over a month to do this.
