The remembering technique from mind maps or notes goes.
Once a day for 3 to 5 minutes for one week
Once a week for 3 to 5 minutes for 4 weeks
Once a month for 3 to 5 minutes for 6 months
From there once a year will help you remember at least 60% but if you actually use the information, you'll be remembering it well within a few weeks.
