Customer Testimonials

I originally failed my first Clin SIM while using another program, but with the help of Tutorial Systems I just passed the SIM. Their staff gave me the confidence to keep going and it helped tremendously. This program is amazing and I would recommend it to anyone in need of passing their exams! - Emily, Portland, ME

I passed my CRT exam today with a score of 86%. Thanks to your review, there were no surprises on the exam! - Ruddy V., Boynton Beach, FL

I can't thank you enough for taking the time to talk me through all of the important details to help me pass. It helped me put the missing 'puzzle pieces' all together. I am extremely grateful for your very affordable online program! - BM, Des Moines, IA
