Find several study environments where you work best, and change places when you find your current work environment too comfortable or distracting.
When finding study environments, choose a place you know you work hardest in (a quiet library, a classroom with background noise, etc.).
Try the Pomodoro Technique: break up study time into 25-minute chunks and take five-minute breaks in between. Search for Pomodoro apps to help you focus.
Shorter, intensive studying sessions are better than long periods of drawn-out studying.
Write notes or acquired information down to help memory retention.
Self-testing improves long-term memory and the ability to retrieve learned information.
The Study Cycle consists of different types of learning (reading and hearing) and enforces repeated reviewing. Understanding it can create a more effective learning process.
Try spaced repetition: review consistently and constantly to avoid the forgetting curve (which explains how information is lost when there is no attempt to retain it).
Try to explain problems and concepts to yourself as if you are the teacher. Explain the material out loud, and it will be easier to find where you are struggling.
Try different types of memorization techniques to discover how you can memorize effectively. Rewrite/retype notes, repeat information over again, use flashcards and mnemonic systems, chunking (group information into larger units), associate information with something familiar, or use the memory palace.
