I am starting the preparation from today and just started the Official Study Guide. I am expecting that I could finish this also by December 2021. I am going to setup a disciplined time to study for this for 3 months.
Well, 2021 got away from me. I now have a CCSP exam date of 4 February, a Friday, so I can either go home and drink beer for a successful test or drink something harder to ease the pain of failure.
Currently watching Mike Chapple's LinkedIn Learning videos (free!) and using Boson and Aris Athanasiou's Udemy practice tests (these are really difficult and stress me out like the actual exam).
The OSG and matching practice test book for my books of choice.
