Simulated time duration is a big help

So i had 90 minutes in total to crack the NCIE SAN Specialist, ONTAP certification exam. As it was my first attempt, i was wondering how would i cope up. Then i came across the NS0-520 simulated tests. These tests need to be performed in similar 90 minutes and i was glad i could practice in timed environment which was fruitful.
