I've noticed many here have at least 4 certifications.
I just would like to know if any of you had to forget what you learned from a previous certification path to learn your most current one you have or are working on?
For me, the only cert I've ever had is the CCNA R&S.
Over the past few years, I've come to realize that the way my brain works is if I'm going to study a specific I.T. subject, I have to go all in on THAT one specific subject and not worry about the others.
The nature of I.T. material makes it that way for me at least.
For instance, if I were to go after an A+ certification, I fear I would forget what I know about Cisco R&S in the process of getting my A+.
Does anybody else here have this concern?
As well, I work during the days and only have so much time to study something anyways.
