Can't you print it, into PDF? Use online converters, it’s easier. Related to exams, NSE is pretty good one, but when I was taking decision I chose Cisco. I was learning pretty good, so I was prepared for every exam, and Cisco became an attraction to relieve the stress. The information given there is so modern. I’ve passed this exam on SPOTO. Very good service and I’m really happy that I’ve chooses exactly those one. Certificate of Cisco is a very useful thing , just try! I was thinking about NSE, but it was too easy for me, don’t know why, but it was so... Maybe for you it’s better, but maybe you need to try.
