Hey @AnumaMaryjane
What are you trying to learn on the ISC2 learning platform? You can become an ISC2 Candidate by signing up for the ISC2 Certified in Cybersecurity training (free, AMF applies to membership and successful certification in the CC).

Please reference this forum post regarding your interest in becoming an ISC2 Canidate/Member

You can become a Canidate if you register for training and fill out the proper application for such training/certification. Once you are a Canidate, you must complete a certification to be recognized as an ISC2 Member -- as far as I am aware. The ISC2 CC is a great start!
