When filling out the CAT 2025 application form, which is released on August 1, 2025, you should be vigilant to avoid common mistakes. These errors include failing to verify the eligibility criteria beforehand, entering incorrect personal information such as name or educational qualifications, carelessly selecting unsuitable test cities, and uploading photographs and signatures that do not meet the specified format and size requirements.

A thorough review of the entire application before final submission is essential to prevent these oversights and ensure a hassle-free process.

Common Mistakes While Registering for CAT 2025

These are a few common errors that students make when registering for CAT 2025:

Mistake 1: Incorrect Information When Creating Your CAT Login

Creating your CAT login is the crucial first step, and any errors made here are permanent. The basic information you enter-such as your name, date of birth, email address, and phone number-cannot be changed later. If you make a mistake, you'll have to start the entire registration process over from the beginning.

  • Name: Your name must be an exact match to how it appears on your Class 10/SSC certificate.
  • Details: Ensure your date of birth, gender, address, and category (Gen/EWS/SC/ST/OBC/PwD) are all selected correctly before proceeding.

Mistake 2: Incorrectly Entering Personal Information

Entering inaccurate personal details is a serious error that can lead to your CAT application form being rejected. This information is cross-checked throughout the entire admission process. Any discrepancies found, even in later stages, can cause significant problems. Therefore, it's crucial to double-check all personal information to ensure it's accurate and matches your official documents before submitting your form.

Mistake 3: Incorrect Academic Information

Your academic qualifications are a critical part of your CAT application. Errors in this section can lead to your application being rejected, so it's vital to double-check all details before submitting.

When filling out the third page of the CAT 2025 online form, you'll need to enter your marks for Class 10, Class 12, your bachelor's degree and any other degrees.

  • Entering Percentages: The form provides a column with the formatnn.
    • For scores between 45% and 99.99%, use only two digits before the decimal point (e.g., 96.50).
    • The first three digits (nnn) should only be used if you scored exactly 100%.
    • Do not use a prefix '0' (e.g., 096.50 is incorrect).
    • Percentages can be entered with up to two decimal digits.

Mistake 4: Uploading Incorrect or Illegible Documents

A frequent error during CAT registration is uploading documents that fail to meet the specific requirements set by the exam authorities. Your application requires a photograph, signature, and any relevant reservation certificates to be uploaded. It is crucial to ensure these documents are in the correct format, size, and resolution, as submissions that do not meet these specifications will be rejected.

The following lists the requirements for the documents needed to complete the CAT application process:

PwD CertificateMust be downloaded from the official website-PDF-

Mistake 5: Incorrect Work Experience Information

While work experience is not a mandatory requirement for CAT registration, it is a preferred attribute during the admission process. If you choose to include your work experience, you must ensure all details are accurate. It is crucial to verify that your experience will be recognized by the exam authorities before you fill out the form. Any incorrect information about your work history can lead to significant issues during the CAT selection process.

Mistake 6: Not Reviewing Before Making Payment & Final Submission

The CAT 2025 registration fee is INR 2500, and once paid, no edits can be made to your application form. To prevent your fee from being wasted due to errors, it is essential to take these two steps before payment:

  1. Gather All Materials: Before starting the 30-minute application process, have all your required documents and information ready.
  2. Conduct a Final Review: Carefully review every page of your application form to ensure all details are correct and complete before proceeding to the payment and final submission.

Other Common Mistakes While Filling CAT 2025 Application Form

Beyond the primary errors, applicants should also be mindful of the following mistakes to ensure a successful application:

  • Not Checking Eligibility Carefully: Before applying, you must verify all eligibility criteria, including minimum academic qualifications, nationality, and category. You are required to have a bachelor's degree with a minimum of 50% aggregate marks (for General, EWS, and NC-OBC candidates) or 45% aggregate marks (for SC, ST, and PWD candidates).
  • Not Having Documents Ready: To avoid mistakes and a rushed process, it's essential to gather all required documents and information beforehand. This includes details from your Class 10th marksheet onwards, caste certificates, and payment method information. Remember that fields marked with an asterisk (*) are mandatory. Ensure your email and mobile number are valid, as you will receive important OTPs and your CAT user ID and password.
  • Not Using a Correct Browser: The CAT conducting body recommends using specific browsers to prevent technical issues. A minimum of one of the following should be used before launching your application:
    • Microsoft Edge: Version 80 to 103
    • Google Chrome: Version 59 or above
    • Mozilla Firefox: Version 56 or above
  • Hurrying Through the Application Process: Since CAT registration is your gateway to top B-schools, it is vital to take your time. Before the final deadline, you can review and change your application as many times as necessary by saving it and logging in later.
  • Choosing the Wrong Test Centre Cities: There are a maximum of six test city preferences available. While your first choice is often accommodated, this is not guaranteed. Carefully select all six options based on convenience, travel time, and logistics, listing them in your order of preference.
  • Not Having a List of Programs Ready: While you can select all programs, it is a significant mistake not to confirm your eligibility for each one. Some programs, such as Executive MBA or one-year MBA programs, are not open to fresh graduates. Similarly, some specialized programs (e.g., IIMs- ABM and FABM programs) have specific educational background requirements.Making a list of the programs for which you qualify is essential before completing the application.
