I had Lahari as my instructor, and I had very high hopes for this course; however, my SAT score did not meet my expectations. I took the course in august, so I completed every single assignment until the end because my school started. Therefore, I did whatever I could on my behalf to succeed. The issue is that my instructor was too focused on the nonsense going on in the chat, which caused us to never be able to finish what was on that day's agenda. Also, she was somewhat rude and condescending. Additionally, way too much time was spent on reviewing missed questions from homework/practice tests. I understand it's important to go over these questions and learn to improve from them, but I don't think a whole hour is necessary. Overall, I am very disappointed and sad my parents paid $800 and it ended off not paying off and I can't even get the money back because of the strict rules for the assignments.
