Good afternoon,
My name is Boris and I'm 26 years old. I would like to continue to obtain Microsoft certifications but I have some troubles finding the right path. At the end of last year, after studying for a long time and having some private time consuming issues, I finally got my MCSA 2008. I was so happy

At the beginning of 2017 I started my new job as a system administrator (after 3 years being in a support function) and trough the year I have learned a lot. However, I want to get on with the certifications again (and learn new stuff).
I have the book "Upgrading your skills to MCSA: Windows Server 2016 (70-643)" right in front of me but browsing though I'm in doubt if it will be realistic for me to pass this in the coming months. I think I may lack experience at the moment cause at the job we are not working with 2016 and the books says it's not designed to teach you new things....
Also it took me +/- three years to complete the 70-640, 70-642 and 70-646 exams. The last exam was the most hard one I think, almost gave up on it

Would it be possible for me to pass the 70-643 exam next year if I had a hard time finishing the exams mentioned above?
Another possibility would be to 'start over' and study for 70-740, 70-741 and 70-742. ..
I am very curious what you guys can recommend me to do
