During this stage, applicants must provide their basic information, including name, Date of Birth, Email Address, and phone number, to proceed with the application process. Your name must be entered exactly in the same pattern and style as it is written in your class 10/SSC certificate.

#Mistake 2: Entering Personal Information Incorrectly

The personal information of a candidate is a crucial part of the CAT application form, and it is cross-checked multiple times during the entire CAT admission process. Therefore, if any mistakes are made when entering the personal information of a candidate, it will lead to the rejection of the CAT application form. Candidates may also face issues during the later stages of the CAT administration process if these mistakes are not found and rectified in the registration process itself.

#Mistake 3: Entering Academic Qualifications/Information Incorrectly

Similar to personal details, the academic qualifications of a candidate are a unique identifier and help the exam conducting authorities separate ideal applicants from mediocre candidates.

The percentage can be entered only upto 2 decimal digits. You are not required to put prefix ‘0’ before writing your percentage of marks as it will not accept it- Correct: 96.50; Wrong: 096.50
