Need good video resources

Starting in 2 weeks my teacher gives us 5 full practice ap tests in an interval of 1 week per test leading up to the official ap test. Its uncurved and worth 50% of my grade and I'm really stressing. I've been starting on old FRQ's but after I learn how to do it the information just doesn't retain its like it only stays in my brain for 3 days before I have to learn how to do it again, because of this I want to learn the concepts with an actual teacher-like "thing" like videos or something. please help
