A+ Institute

I registered for real estate course, online. They gave me access to a website for A+ Institute Learning Management System (online course). As I proceeded through my studies, I found a number of misspelled words which I just "let go", human error. However, as time progressed there became many more misspelled words *and* a couple mistakes which are very clear: "Real property is not Real property". It is suppose to read: "Personal property is not Real Property". I stated questioning the accuracy of the rest of the course, considering I have already found a number of mistakes ... How do I know that the information I am learning is correct, I am not a Real Estate expert so I wouldn't know one way or another. I sent two emails to Mykut Real Estate School letting them know of the errors that I found and called a couple times but never any response. I also emailed A+ Institute and had a phone call with [redacted], manager, who told me that the course is 500 pages, I should expect mistakes. Honestly, no I shouldn't. I am paying $429 to learn from the course I am taking, I shouldn't have to figure out what a sentence is suppose to be w/ the wrong/misplaced words, spelling errors.
