### 2/5 — Ophthalmic tech

*2016-05-09, version 1.1*

I bought this app for 6$ and within  the first 2 tests found that there is a problem -I am answering correctly and being marked as incorrect . Overall I like the app but wish there could be some improvement .

### 5/5 — Great app

*2016-05-27, version 1.1*

This app is great for studying for the COA. The test questions are similar to the real exam. And the best part is that it shows and explains your incorrect answers after the test is done. Really helped me pass the COA exam.
