First, we offer the ability to test drive a group course for free. You can try the course (by being in 1 live class) without the obligation to enroll.
Second, our teachers are cherry-picked.
Third, parents and students have the option to re-watch the session allowing for better understanding.
Fourth, our groups are small (less than 20) allowing for better understanding.
Last but not least we offer a TA (teacher assistant) who is handling all the student questions. The main teacher is giving the lecture and the TA collects and answers the questions in private (with a private chat) allowing for privacy and no bullying!
