Challenging environment like actual exam

I used to get so nervous even while giving mock tests for SAP CO Certification Exam online. The simulated tests are very close to the real deal. Same syllabus, timings, scoring system and even the questions. So i decided that if i excel in these tests, i would definitely be able to clear the C_TFIN22_67 exam. I actually did. i passed exam and am very happy with my score.
