It continues to ask questions about ears when it should only be for eyes. Took my money and didn’t learn anything. Disappointing for sure. -- Eye Nerd, 2025-02-17 ### *---- "Inaccurate" A lot of the answers are inaccurate. I work for a strabismologist who helped clarify several of the answers, and they were incorrect on the app. Kinda want my $10 back. -- eac2914, 2025-01-08 ### *---- "COA" Horrible, don’t waste your money. Questions about otolaryngology? This is more for COT, COMT and Optometric questions. -- Sandman 433343, 2024-08-22 ### ***-- "Has potential" The design of the app is great. The questions not so much. First, there are questions in the app about ears which need to be removed because it is an certified ophthalmic assistant test, it should only relate to eyes. Secondly, some questions had abbreviations that I had no idea what they were and then were not explained in the explanation. I think the writer of the questions should consider reviewing the IJCAHPO test overview for COA and the Ophthalmic Medical Assisting book released by the AAO (American Academy of Ophthalmology). -- Mon_Alisa, 2021-08-23 [View all COA Practice Test Prep reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## COA Practice Test Prep In-App Purchases | Item | Price | |------|-------| | COA Practice Test Premium | $9.99 | ## Apps Similar to COA Practice Test Prep - [DSST Ethics America Prep](https://apptail.io/app/dsst-ethics-america-prep-mRyl/united-states) - [Cosmetology Exam Prep Test](https://apptail.io/app/cosmetology-exam-prep-test-CvMn/united-states) - [DSST Organizational Behavior](https://apptail.io/app/dsst-organizational-behavior-LPRn/united-states) - [HRCI PHR & SPHR Exam Test Prep](https://apptail.io/app/hrci-phr-sphr-exam-test-prep-TUmo/united-states) - [ABA Exam Prep & BCBA Test 2025](https://apptail.io/app/aba-exam-prep-bcba-test-2025-qtvo/united-states) - [AMT RMA Practice Test.](https://apptail.io/app/amt-rma-practice-test-OoVu/united-states) - [ABO Exam Prep](https://apptail.io/app/abo-exam-prep-kVCv/united-states) - [COA Practice Prep Test](https://apptail.io/app/coa-practice-prep-test-WzKv/united-states) - [CCMA Exam Prep Flashcards 2026](https://apptail.io/app/ccma-exam-prep-flashcards-2026-MSPv/united-states) - [CCB CHC Exam Test Prep 2026](https://apptail.io/app/ccb-chc-exam-test-prep-2026-QrSv/united-states) ## COA Practice Test Prep Available In - [United States](https://apptail.io/app/coa-practice-test-prep-hKcf/united-states) - [Ireland](https://apptail.io/app/coa-practice-test-prep-hKcf/ireland) - [Lebanon](https://apptail.io/app/coa-practice-test-prep-hKcf/lebanon) - [Canada](https://apptail.io/app/coa-practice-test-prep-hKcf/canada) - [Philippines](https://apptail.io/app/coa-practice-test-prep-hKcf/philippines) - [Saudi Arabia](https://apptail.io/app/coa-practice-test-prep-hKcf/saudi-arabia) - [Latvia](https://apptail.io/app/coa-practice-test-prep-hKcf/latvia) - [Kuwait](https://apptail.io/app/coa-practice-test-prep-hKcf/kuwait) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
