The ABO Practice Quizzes are designed to allow you to practice ABO concepts a little every day. To get the best results, we recommend taking one quiz per day for 30 days. A little practice every day is better than a lot of practice all at once!
Each quiz has about 20 questions. The topics covered on the quizzes are:
- Ocular anatomy
- Refractive errors
