Optician Essentials and Advanced Exam Practice Test

Liking the book so far. The formating (or lack thereof) make it a little hard to follow. It doesn't fully expand on any topic but briefly touches on a variety of topics.Questions 50-54 seem off to me... I must be missing something. I can calculate the rest of the answers but for these my answers aren't even one of the options :(There are very few practice tests to there so I appreciate it

Good abo exam review, but some errors specially in the question/answer area

I'm not commenting on the content yet, as I have not finished the full book, I will update when I have. I will say that I was very surprised that at this price, there were no page numbers. It also lacks an index and was not professionally edited. Hopefully the author will address these issues in a future edition.There is a dearth of material available for this subject matter, so I was very happy to see this book. I do hope the content is more complete than the presentation.

Easy to learn the test
