So they pay everyone to review 5 stars and once you link and approve the review they pay you a discount for the rest of your assignments. I would never recommend them, bad communication and I know I should have done the assignment myself. But this companies service is bad, don't go with them. I had them do one of my tests online and they had "experts" look at it and they realized they are too complicated for them ON THE DAY. They had past test examples, solutions, course notes and everything. I only got my refund because of paypal's policy.
