Good, but…

It’s a good app! But it doesn’t acknowledge that I finish my lessons, this results in having to do them again.

The best paid resource out there

I am really glad I went with this app even though it is paid, because I had already exhausted the free resources out there and still needed further improvement in my score (SAT). It really has everything

Thank you for your kind words. We have continued to add features since your review, and we wish you every success on test day.

Sickening greed

You guys are so greedy what the heck. A few months ago I used one prep completely free, and what stood out about you guys was that it was not greedy money farming slop.

Now you suddenly want to charge almost $100 a month on this tool? This greed is absolutely sickening and I am so disappointed.

Needs Rework

It is a good website and helps learn however the app should be ideal to use but the question bank won't even load no matter what. It is very laggy and in need of updates.
