@leatherneck3041 affiliate membership basically indicates a member of the CFA Institute that hasn’t fully fulfilled one or more of the Regular membership requirements (often either yet to pass Level 3, or work experience requirements). As far as I know, all society benefits still apply to Affiliate members.
As to your personal situation – it’s hard to give advice without knowing much more. Based on what I can see, honestly CFA may not be the right path for you if your plan is to pursue this part-time.
