Answer: study it for like a week because you can remember for the rest of your school year.
Explanation:
I know because when I was in 7th grade I had a schedule for all of my classes and I have to practice for the first school week and then the rest of the year I remembered my schedule for the whole 7th grade year it got easy when I knew I can just go to my classes without looking at my class schedule.
You could get a planner to write down times for things you plan to get done. I've found if I write down a time to get something done and then check it off when I've done it I feel more inclined to actually do it. Just write down a time frame for studying each day, or every other day, or simply when you have time for it. Whatever suits your needs and gets the job done.
