Pros:

• It offers schedule flexibility to its users.

• Provides highly qualified tutors.

• Collect or tolerate study groups of up to 3 students: making it much easier to share experiences and knowledge.

• It is one of the largest communities in the world, which gives it strength.

• It is more accessible than other similar services, so it becomes more accessible to those with low resources.

Cons:

• Not all tutors are good, I have read of other users who have complained about certain tutors.
