How to Memorize Geometry Does This Sound Like You?
You sit with your math book for 2 hours.
You read the same formula 10 times.
You close the book and… blank.
Next day in the exam hall, you remember the diagram but not the formula.
Sound familiar?
Listen, I’ve mentored over 5,000+ students for Govt Exam Preparation 2025, and I can tell you this:
You are NOT weak in math. You just never learned HOW to remember formulas.
Today, I’m going to fix that problem. Forever.
The Reality Check: Why the “Old Way” Doesn’t Work
Let me be honest with you.
The way you were taught in school is completely useless for competitive exams.
Here’s what most students do:
- Read the formula 50 times (thinking repetition = memory)
- Write it 100 times in a notebook (wasting time)
- Try to “understand” every formula deeply (not needed for exams)
Here’s the truth:
In SSC, Railway, or UPSC exams, you need to solve questions in 30-45 seconds. You don’t have time to “derive” formulas.
You need instant recall. Like muscle memory.
And for that, you need a system.
The Solution: My 4-Step Formula Memory System
I’ve used this exact method to help thousands of students crack Sarkari Naukri exams. It works because it’s based on how your brain actually remembers things.
Step 1: Group Formulas by Shape (Not by Chapter)
Your textbook groups formulas by chapter. That’s the problem.
Your brain remembers patterns, not chapters.
Here’s how to group them:
Group A: Triangles
- Area = ½ × Base × Height
- Perimeter = Sum of all sides
- Heron’s Formula = √[s(s-a)(s-b)(s-c)]
Group B: Circles
- Area = πr²
- Circumference = 2πr
- Area of sector = (θ/360) × πr²
Group C: Quadrilaterals
- Rectangle: Area = l × b, Perimeter = 2(l+b)
- Square: Area = a², Perimeter = 4a
- Parallelogram: Area = Base × Height
Group D: 3D Shapes
- Cube: Volume = a³, Surface Area = 6a²
- Cuboid: Volume = l×b×h, Surface Area = 2(lb+bh+hl)
- Cylinder: Volume = πr²h, Curved Surface Area = 2πrh
Why this works: When you see a circle in the exam, your brain automatically recalls “Circle Group” formulas.
Step 2: Create Memory Tricks (Not Rote Learning)
Let me show you examples:
For Triangle Area:
- “½ Baby Height” → ½ × Base × Height
For Circle Formulas:
- “Apple Pie Are Squared” → A = πr² (Area)
- “Cherry Pie, 2 Are” → C = 2πr (Circumference)
For Cuboid Volume:
- “Love Boys Have” → l × b × h (Length × Breadth × Height)
Make your own tricks. The sillier, the better. Your brain remembers weird stuff easily.
Step 3: Use the “15-Minute Daily Drill” Method
Here’s what you do every single morning:
Morning Routine (15 minutes):
- Minutes 1-5: Look at your formula sheet (don’t write, just see)
- Minutes 6-10: Close the sheet. Write all formulas from memory
- Minutes 11-15: Check mistakes. Rewrite only the wrong ones 3 times
That’s it.
Do this for 21 days straight. I guarantee you’ll never forget these formulas.
Why 21 days? That’s how long it takes to build a habit and move information from short-term to long-term memory.
Step 4: Practice with “Formula Application”, Not Just Memorization
Knowing the formula is 50% of the battle.
Using it correctly is the other 50%.
Here’s what you should do:
- Solve 10 previous year questions daily (SSC CGL, Railway, or UPSC prelims)
- Focus on speed, not perfection
- Time yourself: 45 seconds per question maximum
The magic happens when you solve questions WHILE the formula is fresh in your mind.https://www.khanacademy.org/math/basic-geohttps://www.khanacademy.org/math/basic-geo
Pro Tip: The “Secret Sauce” for Permanent Memory
Here’s something I don’t usually share publicly.
The problem is NOT that you can’t memorize formulas.
The problem is you don’t have them organized in ONE place.
Most students waste 30 minutes searching through 5 different notebooks to find the right formula during revision.
Here’s what toppers do:
They create a one-page formula cheat sheet for quick revision.
- All formulas on 1-2 pages
- Color-coded by topic
- With memory tricks written next to each formula
- Laminated, so you can carry it everywhere
I’ve created a similar ready-made formula sheet that my students use during their last-minute revision. It has:
✅ All Geometry & Mensuration formulas (2D & 3D)
✅ Memory tricks for each formula
✅ Quick revision notes
✅ Most commonly asked exam patterns
[This is where you will add your PDF product link later]
You can create your own version too. Just follow the format I’ve shown above.
The Comparison: Old Way vs. Smart Way
| Old Method (Doesn’t Work) | Smart Method (Works Every Time) |
|---|---|
| Read formulas 100 times | Group formulas by shape |
| Write in random notebooks | Create ONE cheat sheet |
| Try to “understand” everything deeply | Use memory tricks & patterns |
| Study for 3 hours once a week | Practice 15 minutes daily |
| Hope you’ll remember in the exam | Train for instant recall |
Your 30-Day Action Plan for Exam Strategy
| Week | Action | Goal |
|---|---|---|
| Week 1 | Group all formulas by shape. Create memory tricks. | Build your formula sheet |
| Week 2 | 15-minute morning drill daily. No excuses. | Move formulas to long-term memory |
| Week 3 | Solve 10 previous year questions daily. Time yourself. | Build speed & accuracy |
| Week 4 | Full mock test. Identify weak formulas. Revise only those. | Final polishing |
Follow this plan, and you’ll never forget a formula again.
Conclusion: You’re Closer Than You Think
Listen.
I know you’re tired.
I know you’ve failed before.
I know your parents are asking “Kab tak padhoge?”
But here’s the truth:
You’re not failing because you’re not smart enough.
You’re failing because no one taught you the right method.
Geometry and Mensuration are scoring topics in every Govt exam. SSC CGL, Railway NTPC, UPSC Prelims—they all test the same 40-50 formulas.
Learn them once. Use them forever.
Start today. Start with just 15 minutes.
And remember: Sarkari Naukri Tips are useless if you don’t take action.
Your future is waiting. Go get it.
