Simulated time duration is a big help

So i had 120 minutes in total to crack the 300-101 certification exam. As it was my first attempt, i was wondering how would i cope up. Then i came across the CCNP Routing and Switching simulated tests. These tests need to be performed in similar 120 minutes and i was glad i could practice in timed environment which was fruitful.
