Nothing is tough after practice

Identify differences: Network Programmability Fundamentals, Data models and Controllers topics are those that are very tough. However, i did not fear and kept on giving 300-550 simulated practice tests on a daily basis in a bid to prepare for the Cisco NPDESI certificate exam. The more questions on these topics i answered, the more easy it became for me and i finally got the confidence to clear the actual exam.
