First, to eliminate external interference, we must first find a quiet environment suitable for study. If we read books in the park, the effect will definitely be unsatisfactory. The second is to eliminate inner interference. When studying, don't think about anything else, concentrate on your study.
Step 2 stay relaxed
People's memory is curved. Don't study blindly, but face up to it. Learning needs persistence. Don't take learning as a burden, but as a pleasure, and find happiness from learning!
3. Learn to understand memory
