Pros
Convenience of tutoring on your own time at home or elsewhere, computer logs time so you get paid for every second you spend tutoring, easy to use interface that allows to draw diagrams and edit essays (I think there's even a coding interface for the computer science folks out there). Payment is consistent and transferred to bank account within 3-4 days so this is just an INCREDIBLY convenient tutoring company for tutors who don't like to travel to student's homes or have a unpredictable schedule.
Cons
Sometimes I can have the website open for hours but have no one request me for a tutoring session. Also, sometimes kids just want to you answer homework questions without paying (they don't have a credit card); you can choose not to tutor them though, which is great. Very few complaints. This company/tutoring opportunity is unique and convenient for both the students and the tutor.
