😅 My Honest Experience
When I solved 100 Maths questions:
- I got tired after 40
- Made silly calculation mistakes
- Lost marks in easy questions
💡 What Helped Me
👉 Practicing daily
👉 Revising formulas
👉 Improving speed
🎯 My Strategy
- First solve easy questions
- Skip lengthy ones
- Come back later
Math Practice – Continued (Real Exam Style + My Notes)
So after solving first 100 MCQs, I realized one thing 😅
👉 I was making mistakes not because I didn’t know… but because I rushed.
Like seriously, I knew formulas… but still wrong answers.
Then I started writing small formula tables + tricks.
That helped me a lot. So I’m sharing same with you.
📊 Important Math Formula Table (Must Revise Daily)
| Topic | Formula | My Simple Trick |
|---|---|---|
| Percentage | (Value/Total) × 100 | “Out of total → ×100” |
| Profit | SP – CP | Selling > Cost = Profit |
| Loss | CP – SP | Cost > Selling = Loss |
| Profit % | (Profit/CP) × 100 | Always divide by CP |
| Simple Interest | (P×R×T)/100 | PRT/100 (easy) |
| Average | Sum / Number | Total ÷ Count |
| Speed | Distance / Time | D/T |
| Distance | Speed × Time | S×T |
| Time | Distance / Speed | D/S |
| Ratio | a:b | Simplify always |
| Area (Square) | side² | side × side |
| Area (Rectangle) | l × b | length × breadth |
| Area (Circle) | πr² | 22/7 × r² |
🔥 My Personal Trick
I didn’t try to learn everything at once.
👉 I revised this table daily for 5–10 minutes
👉 Then solved MCQs
That’s it. Simple but effective.
