I am using TrainSignal only

I am using trainsignal and I watched all the videos on the 220-701 test, and I took the Transcender practice exam questions and scored 80% or better on all four of there (100 question each) 220-701 test. Is this all I need to do because If scoring 80% or more on all their test is all I need to do before taking the 220-701 as they clam, then I should be more then ready. What do you all think.
