I was a naive student earlier. I did not know how will i appear for the ADM-201 mock tests also, so giving the actual Salesforce Certified Administrator certification exam seemed like a distant dream. However, giving mock tests seemed so beautiful gradually that i got hooked on to them. In a matter of two months, i was completely prepared for the exams and felt quite good when i gave the real one. The balance of real-time and practical questions opened up my mind nicely.
