Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
This tutoring impressed me a lot! not only did the tutors helped me with currect lessions i needed help with, but they prepared me for future trig lessons to come and very useful imformation - gabriella
