My ISSA chapter is offering free CISSP training over the course of 3 Saturdays for 8 hours each. Both ISSA members and instructors at my college recommended that I attend. Some ISSA members also formed a study group to help one another that I was also invited to. They are both are telling me to
strive for a CISSP certification while I am studying Security+. I've already had courses in Security+, CEH, SSCP, & CCNA Security at college so I am aware of security concepts, practices, and a few domains.
However, other than getting an easier time with understanding MSISA courses at WGU, I don’t know if it is going to be too much of a credential to me. I am still working on my BS: Computer & Information Science with a concentration in Network Security while studying for certifications. My work history is just retail totaling 16+ years (7 years at a Kmart and 9 years currently at a Sam's Club) so I have no IT professional work experience.
From my understanding, if I do pass and the exam, I would only be awarded “Associate of ISC2” and I would have 5 years (or 4 years after I gain my degree or Security+ cert) to gain security experience in two domains followed by an endorsement. I don’t see how that would be any different from passing a SSCP exam and earning the same title. Without the proper CPEs, it is just going to go into default after 3 years anyway, wasting my time and money right? So my question for the knowledgeable members on this forum, should I just forgo the CISSP training and certification since I am under qualified to do anything with it?

Maybe I’m low-balling myself in what they see in me & my studying tenancy, however, I am just getting the impression that the ISSA members and my instructors don’t see how the CISSP may be realistically worthless to me at my level. That is why this board's honest, professional opinions are appreciated & matter to me on what you think I should do.
EDIT: I did want to misconstrue the point that I have no problem studying for it; I just do not want to waste my money and time (a lot of time is needed for this studying) if the certification won't help me in out at my current level.
