My wish was to give SAP System Administration (Oracle DB) certification exam. But I am new to this and was worried where I will find practice test. I did not know any seniors who passed out. I asked my friend who suggested me to find on internet. And I found this SAP practice exam. I gave the mock test, C_TADM51_75, a week ago and I was surprised to find such a good test online. The practice exam is good, score 90% in final exam. I will give more tests to become the best in exam and pass it.
