An OTP will be sent for verification. Complete the OTP verification to create your CAT 2026 registration profile. After successful registration, you will receive your login credentials.

Step 3: Fill in Personal Details

Log in to your account and begin the CAT 2026 application form.

Enter your personal information carefully, including:

• Father’s/mother’s/guardian’s details
• Gender
• Category
• Nationality
• Communication address
• Email ID
• Mobile number

Check your name and date of birth carefully before moving forward.

If you belong to a reserved category, make sure the category information and supporting certificate details are correct.

Step 4: Enter Academic Details

The next important section is your educational information.

You will need to provide details related to:

• Class 10
• Class 12
• Bachelor’s degree
• Other professional qualifications, if applicable

Enter marks and percentages exactly as required by the form and according to your official academic records.

Do not guess your percentage.

Step 5: Add Work Experience

If you have work experience, enter the relevant details such as:

• Job role/designation
• Duration of employment

Work experience is an optional section for candidates who do not have professional experience.

Freshers can proceed without adding work experience.

Step 6: Select IIM Programmes

The CAT application form 2026 also allows candidates to indicate their preferred IIM programmes.

Read the programme options carefully and select the courses you want to be considered for.

This section is important because your CAT application is not simply about taking the exam; it also connects your application with the programmes and IIMs you are interested in.

Step 7: Choose CAT 2026 Test Cities

Candidates need to select their preferred CAT test cities while filling the application form.

According to the current CAT 2026 registration information, candidates can select up to five cities in order of preference. Test-centre allotment remains subject to availability.

Choose your cities carefully instead of selecting locations randomly.

Step 8: Upload Photograph and Signature

This is one area where many applicants make mistakes.

For CAT 2026, the photograph and signature should meet the specified format and size requirements.

The photograph should have a white background and should not be more than six months old.

Always check the preview after uploading your files. A blurry, distorted or incorrect image can create an upload problem.

CAT 2026 Application Fee

After completing the required sections, you need to pay the CAT 2026 application fee.

For CAT 2026, the fee is:

• ₹2,700 for General candidates
• ₹1,350 for SC/ST/PwD candidates

The fee is paid online during the application process.

Before making the payment, carefully review the complete application.

Step 9: Preview and Submit CAT Application Form

This is the step you should never rush.

Before clicking the final submit button, check:

• Name and date of birth
• Category
• Academic marks
• Graduation details
• Work experience
• Programme preferences
• Test city preferences
• Photograph
• Signature
• Payment details

Once everything is correct, submit the CAT application form 2026.

Save your confirmation and application details for future reference.

Common Mistakes to Avoid While Filling CAT Form 2026

Avoid these common mistakes:

• Entering incorrect academic percentages
• Selecting the wrong category
• Uploading an incorrect photograph or signature
• Using unsupported image formats
• Ignoring the test-city preference
• Waiting until the last day to register
• Entering incorrect personal information
• Failing to preview the completed form

The CAT 2026 image-upload system accepts JPG/JPEG files, and files exceeding the specified size or dimensions can cause upload errors.
