Good book. I learned good concepts. With all respect you deserve, I found on page 96 that solution to Problem III (2), section (a) could have an incorrect answer. I think it should say “…the error was made have been closed.”.
Good afternoon, The text and content is easy to read, and the information is very practical. 
Clear and concise
Good content and a little above my skill level. I had to go online to get some definitions and fill in some of the gaps. I feel students should be tested before receiving this course.
This is my 2nd time at this book. 1st in class and now as an employee. I find I need to master this book more since I hardly ever do manual accounting.
for me it was great.
A very well-written and comprehensive review.
Great step by step instruction
very good
Good Information
Great
Excellent book for entry level bookkeeping/accounting student that wants to gain a better understanding of troubleshooting the Trial Balance and making various entries for the correction of errors.
This is a matter of simple observation and sound knowledge of the accounting equation. Allocating errors are the most critical lately  
Very easy to understand. Plenty of practice. I really enjoyed studying from this book. Great tool to use for teaching yourself or even just brushing up.
Excellent course very informative.
Very informative and easy to follow
too much time on bank recs and on errors the bank made, but good at finding transpositions etc. there should be more time on looking at the actual balance sheet and profit and loss to find errors
Satisfied with the overall experience.
Also not for the beginner! Course presumes you have working knowledge and/or education in the field of accounting.
Well, I am totally dissatisfied with the entire Bookkeeping course that I took. The test appears to be dated. The material in the textbook and the test are different. I would like a refund for the money that I paid for testing. This is not a course that I would recommend to others. I would rate this as a 1/2 star.
Very clear and to the point.
great help in learning more about fixing errors
Excellent
some areas were confusing for me but others very clear
I didn’t actually take this course. I am CPE coordinator at my CPA firm and we purchase these to help our new hires. We find them very useful for refreshers for newly graduated, but inexperienced accountants.
Great tips for finding errors!
Helped refresh me on how to fix Accounting Errors
Well written, easy to understand course.
In depth and precise.
Same comment as adjusting entries.
