Once i submit the assignment, so how much you will charge for 1 assignment? and how can i make sure you done my assignment and let me see before payment?
The price of your assignment depends on its complexity and deadline. We start working on it only when payment is received, so you cannot see the work before. But if the level of work is inappropriate, we return you part of paid money or even make full refund if the solution was not provided or it was fully incorrect.
