Why CAT Registration Needs Extra Attention
With over 3 lakh applicants every year, CAT is a highly sought-after MBA entrance exam in India. However, every year, many forms are rejected or require correction due to preventable errors. Follow these 5 checkpoints to complete your application smoothly and maximize your admission chances.
1. Check Eligibility Before You Register
Before jumping into the registration form, make sure you meet the basic CAT eligibility criteria:
- Bachelor’s degree with minimum 50% marks (45% for SC/ST/PwD)
- Final-year students can also apply
- No age limit for CAT
Tip: If you’re awaiting your final results, select “Appearing” under qualification and upload a relevant document/semester mark sheet.
2. Use a Valid Email ID and Mobile Number (And Keep Them Active)
Your email and phone number are your primary login credentials for CAT:
- All future communication including admit card, results, and updates will be sent here
- You cannot change these once the form is submitted
Tip: Avoid using college or temporary emails. Use a Gmail ID you regularly access and keep your phone number active till the admission process ends.
3. Double-Check Academic & Category Details
This is the most error-prone section of the CAT form. Students often:
- Miscalculate percentage (especially for CGPA)
- Select the wrong board/university or course duration
- Upload invalid documents (EWS/OBC-NCL/SC/ST certificates)
Tip: Use your official mark sheets and certificates when filling in the data. For CGPA, follow the university conversion formula. Cross-check each field before submission.
4. Upload Documents in the Right Format and Size
Many forms are rejected due to poorly scanned or wrong-size documents:
| Document | Format | Size Limit |
|---|---|---|
| Passport size photo | JPEG/JPG | 30–80 KB |
| Signature | JPEG/JPG | 30–80 KB |
| Category certificate | Up to 200 KB | |
| PwD certificate (if any) | Up to 200 KB |
Tip: Use a clear white background for your photo and scan your signature with a black pen. Ensure documents are legible and not pixelated.
5. Choose Exam Centers Wisely
You can choose up to 6 preferred test cities. Many students:
- Choose only nearby cities without backup options
- Pick unfamiliar cities during festive travel times
- Don’t consider connectivity and accommodation
Tip: Always select a mix of nearby and well-connected cities. Final allotment is based on availability, not preference order, so plan ahead.
Common Mistakes to Avoid During CAT 2025 Registration
- Using autofill features that enter incorrect data
- Submitting the form in haste without reviewing

FAQs on CAT Registration 2025
1. What if I make a mistake during CAT registration?
