🎯 Study Tips

→ Active Learning: Don't just read—implement! Type out examples.

→ Spaced Repetition: Review concepts after 1 day, 1 week, 1 month.

→ Teach Others: Best way to learn is to explain to someone else.

→ Break It Down: Complex topics? Split into smaller chunks.

→ Practice Daily: Even 30 minutes of coding beats weekend marathons.
