They lure you with misguided marketing schemes and just want to take your money. They suck.
Don't use them avoid them. They say that they are going to help you out and they do not do so. Instead, you get the run around answer and they try to steer you towards buying a membership package.
It sounded like a bad deal. After, reading the review I must say I agree 100 percent with everyone else and I recommend you to look somewhere else and not use tutor vista because they suck and they do not fulfill their end of the deal.
