This tutoring sit is scam. They took my two assignments with agreed charge and due date. Before due date, they sent me one solution which included wrong equation and wrong answer. How did they can use wrong equation even use wrong equation, the answer supposed to be right, but it was wrong answers, too. I could not even see what they wrote, but I can see which equation they use because I can not see each one of number and word. It was really blurrly so some of them I can see barely, some of them I can not see them. I asked for clear note, but they never did. I could laugh because they have copied some website program then sent me. I tried to contact them, but they did not answer and they sent me black mails. they still do not give me my money back and the paypal is reviewing this charges.
