I had to get some help with a coursework as my time is quite limited with work, family, home commitments. So tried getting some material to compensate for the time and paid these guys to help me. All they did was to give me a bundle of corrupted PDFs and running away with my hard earned money. I'm writing this to warn everyone of my experience. Please don't waste your time and hard-earned cash. Shop elsewhere and save your energy and distress.
