How is 5 Steps To A 5?

Whenever I try to look up its credibility, like on bestapbooks, they mostly always list Barrons paired with crashcourse books. And 5 steps have been out even in 2001 so after all the years, no credit?? Someone explain pls

Soz, i meant also meant whenever I look at bestapbooks to see which brand is the best for prep

I’ve heard that Barron’s and Princeton Review are best. Personally, I think the most helpful thing is just reading the book. Any shortcut to getting the info usually isn’t as helpful as doing it the right way. Crash course videos come in handy as the picture really sticks in your mind. One thing I thought was strange though was I did check out the 5 steps website last year and took a practice exam on it, and one of the questions from the website was used in the actual exam. It was just one but it made me feel as if I should have maybe used it more often.

Can anyone elucidate on this?

I think I’m going to use 5 Steps for Computer Science A, PR for the Sciences. I’m not sure about Calculus BC, might just go with PR for that too.
