I too passed my CKA. Primarily due to the Kodekloud course. I actually took the LF course and it really didn’t do much at all for me, took Kodekloud’s course, and was way better off.
Practice, practice, practice. Go through the material. Any spot that you go through the labs twice on and still go “I don’t feel comfortable on it”, as in you can’t remember the steps to do it easily, do it another two times. This will ensure you have more than enough time to overcome test jitters etc.
