I would agree with what you said retry. Also, I'd make this point, I'm meditating on Scripture to better understand God's Ways, to know Him better. What comes to my mind is this verse: Psalm 103:7. "He made known his ways unto Moses, his acts unto the children of Israel."
I'm posing the question, do we want to only know about His acts, His actions, what He has done? Those are all good things to know. But do we want also to be like Moses, and to understand and know His ways?
(just a clarification, I used the term "meditating" on Scripture because my experience with this site is that after the verses reach 100%, I haven't really "memorized" them forever to the point where I can recite them. I just want to be transparent about that. Have a blessed day, everyone.)
This help page, hopefully, will help you to understand better. https://learnscripture.net/review-schedule/ I will try to help also. What did you choose to learn? All of Matthew 5? A selection from Matthew 5? Have you tested yourself yet on any of the verses in Mt 5?
Using a spreadsheet for a list of passages. Some of them I "memorized" long ago but now have reset. The spreadsheet determines the next review date. I use the hints and a lot of repetition. Hebrews is a wonderful epistle and I'd love to add that one to my spreadsheet .... someday lol.
