Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Even though I don't feel good, the tutor helped me by totally helping me understand!
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
