## What is COA Practice Test Prep?

Your new best friend in learning COA Practice Test takes test preparation to a new level.

Studying and passing your Certified Ophthalmic Assistant Test will never be easier. WE PROMISE!

In fact, our amazing apps are developed by educators and utilize our proprietary learning technique ELS™ or Effective Learning Strategy.

Learning, studying and memorizing requires you to use your short term memory! 

ELS uses a technique called “chunking.”

In cognitive psychology, chunking is a process by which individual pieces of information are bound together. It is believed that individuals create higher order cognitive representations of the items on the list that are more easily remembered as a group than as individual items themselves.

The bottom line… It works!

### 1/5 — Disappointing

*2025-02-17*

The questions are outdated. 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.

### 1/5 — Inaccurate

*2025-01-08*

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.

### 1/5 — COA

*2024-08-22*

Horrible, don’t waste your money. Questions about otolaryngology? This is more for COT, COMT and Optometric questions.

### 3/5 — Has potential

*2021-08-23*

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).
