Discover how our practice tests have empowered countless students to pass their exams with ease.
I used Prephow while getting ready for the SSAT Upper Level exam. I spent some time with the online exam simulator because I wanted to get used to working through a test under more realistic conditions. It became part of my regular study routine.
I used Prephow for some of my STAAR preparation. I checked the performance tracking after studying to see how I was doing and what I should spend more time on. It was useful to have that information in one place.
I used Prephow when I was studying for the TACHS exam. I paid close attention to the detailed explanations when I got something wrong because I wanted to understand the answer instead of just moving on. That was one of the parts I used most during my review.
I spent part of my ABIM preparation using Prephow. I looked through the performance analytics after my sessions to see where I was doing well and where I needed more review. It gave me something specific to look at when planning my next study session.
I used Prephow while preparing for the CCM exam. I liked having the option to use the printable practice tests because sometimes I preferred studying on paper rather than sitting at my computer. It worked well for the way I usually study.
I used Prephow during my CDA exam preparation, mostly from my phone. The mobile practice test was convenient when I had some free time away from my computer. I could do a little review without having to set up a full study session.
