Assalamu Alaykum Wa Rahmatullahi Wa Baraktuh, May Allah reward you and grant you with goodness. Do we have to memorize the "key terms" in the SOK notes as students of knowledge?

Ustadh AbdulAziz al-Haqqan

They are for your benefit, if you see some terms that are very important then memorize them. The main focus should be on the ayat and ahadeeth and what do they prove.
