OPOTA practice

I am in collage and about to get my bachelors degree and I am planning on going to the police academy. I heard the OPOTA exam is a joke, but I still want to study early because I am fit and PT shouldn’t be a problem. What are the best sites to use when practicing for this exam? I have used 2 sites already but some of the answers are inaccurate on each site. Just wondering any authentic sites to use pratice for the exam!
