It will save time later. The time saved will be apparent when you actually begin your studying. You can concentrate on other necessities, such as highlighting the answers in your notes and reading the texts required for the course. Plan regular study sessions to avoid falling behind. Plan what you will study in those sessions and organize accordingly.
Nothing wastes time more than playing catch-up.
Take short breaks while you study. Set up your study schedule in 20 minute segments. Then break for five minutes. When you come back from your break, start your next study block by reviewing the last material you studied before your break. Create mnemonics, or memory devices, to help you in study.
