Here are a few tips for learning quickly at school

Be an active learner: Instead of just passively reading or listening to lectures, try to actively engage with the material. Take notes, ask questions, and participate in class discussions.
Review and summarize: After each class or study session, review your notes and try to summarize the key points in your own words. This will help you retain the information and understand it more deeply.
Practice recalling information: Quizzing yourself or teaching the material to someone else can help you reinforce your learning and improve your recall of information.
Create a positive learning environment: Find a quiet, comfortable place to study where you can focus and eliminate distractions.
Get enough sleep: Adequate sleep is essential for learning and memory consolidation, so make sure to get enough rest each night.
Take breaks: It’s important to take breaks and give your brain a chance to rest and process the information you’ve learned. Taking short breaks every hour or so can help improve your focus and retention.
Find a study group: Working with a group of classmates can be a great way to review and understand the material, as well as hold each other accountable for staying on track.

By following these tips, you can improve your learning speed and retention at school.
