Superb value for an excellent course

TTP offers a great course that covers all topics for a very reasonable price of 100$/month.

Pros:
- explatations are easy to understand
- important points are highlighted and can be bookmarked for review later
- an excercise right after almost every sub-chapter to solidify the concept learned
- a lot of chapter tests for every topic
- error log
- chat function connects you to one of the tutors
- strategy section teaches you about mindset and test-taking

Cons:
- the first answer you get when you ask a question in chat is mediocre, so you need to ask follow-up questions in order to understand what you wanted to know
- for verbal there are not enough practice excercises or chapter tests (at least for me)

Generally I was very satisfied with TTP, especially considering the price. If you do decide to take this course I would recommend doing additional verbal practice questions here on gmatclub (maybe this only applies to me since I am weaker in verbal than in quant).
