🧠 Exam & Study Tips
- Practice daily: Try two programs a day to build confidence.
- Visual learning: Draft flowcharts before coding—helps understand logic.
- Test edge cases: Use different input values to observe carry/overflow behavior.
- Simulate frequently: GNUSim8085 lets you see register operations and flag settings live.
- Revise smartly: Group programs by theme (e.g., all arithmetic tasks) and review weekly.
