Preperation work for Sys Admin Track Certification

I am preparing for Boot Camp and I wonder if I'm going over board with my prep.  For each exam section such as Object Manager & Lightening App Builder I'm doing all of the the modules and projects listed in that section (that I haven't already done).  If I've already done the module/project I just review the materials.  I'm also doing the samples exams and using the flash cards.
