CPEs for Associates can only be earned from Group A activities. i.e. Ones that are directly associated with the domains of your certification.
So look at the domains of the SSCP and decide how much time you spent learning elements associated with them.
CPEs can be submitted in increments of 0.25 per 15 mins of learning.
More details can be found in the CPE Handbook:
