Challenging practice exam environment

Initially i was like just 210+ practice questions, i will complete them in a jiffy. But when i gave the first mock test, all the overconfidence melted like ice at first sight. 210-451 practice tests are simulated and according to me more tough than the actual CCNA Cloud exam. They grilled me left right and centre and i was a transformed person at the end of it all. Scoring 935 was easy but not the practice sessions.
