What can Naquan do to improve his circuit-learning schedule?
Break these study sessions into smaller chunks of time and spread them out during the day
Change the last Tuesday and Wednesday to use 5-, 10-, and 15-minute chunks
Review for longer periods of time—at least 10 minutes—at the beginning of each day
Shorten the amount of time studying on the last two days, to quickly review the material
