App still has bugs

Hi developer
I purchased this app 2 weeks ago and using it just few days from now.
I can see somebody already mentioned about the questions being chosen different with my choice after finish the test. When I go back to review I can see that. PLEASE FIX ASAP.
And if you can add bookmark questions, that will be great!

Worth every penny!!

I purchased this app a few weeks ago. I went through every practice question and did all the practice tests 2-3 a week. Then, I Would read and review the ESCO literature and highlight all the familiar questions from the app. I ended up highlighting 90% of the book. The best part was that it wasn’t just yellow lines on a page, but the info was actually retained. I received 100% core, 100% type1, 92% type2, 92% type 3. The app had current information, and the exam questions were recognizable. It is Worth every penny!!!

Best App ever used

I don’t usually write reviews, but I just got done taking my EPA 608 universal and PASSED. This app has the EXACT questions that are on the test and that is no joke! Normally they are worded different, nope, exactly. I literally studied this app the night before, last night, just ran through the practice test four or five times each and took my exam today and passed. 6 stars if I could. Great work, worth every penny, cause now I don’t need to pay for another test.
