Do I need to use Tutor service?

Learners who do not use Tutor service are still assisted through Live Support, Discussion, Forum, etc. Therefore it’s not necessary for you to purchase this service.
However, it is advised that you should consider applying for the live class service because you will have an online period per week to learn from a tutor. Furthermore, the tutor will help you learn faster and motivate you to keep learning when you are discouraged. The tutor will accompany you on reviewing lesson contents and practicing speaking skill.
Thus, it is up to your personal needs and financial capabilities that you can decide whether to sign up for the Tutor service or not.
