How to Fill JEE Main 2027 Application Form: Step-by-Step Guide
Common Mistakes to Avoid in JEE Main 2027 Application Form
Candidates should carefully review the information bulletin of JEE Main 2027 before filling out the application form. Understanding the registration guidelines, eligibility requirements, examination papers, and document specifications can help prevent common errors related to the JEE Main form filling process.
Here are 11 serious mistakes candidates should avoid while completing their JEE Main 2027 application form.
1. Confusing State of Eligibility with State of Residence
Candidates sometimes select their current residential state instead of the state from which they passed or are appearing for their Class 12 or equivalent qualifying examination.
The State of Eligibility is generally determined by the location of the institution where the candidate passed or is appearing for the qualifying examination, subject to the specific rules mentioned in the JEE Main information bulletin. It is not necessarily the candidate's state of residence or domicile.
Common mistakes to avoid in the context of State of Eligibility:
Selecting the current residential state instead of the state associated with the qualifying examination. Make sure to add your address in the place of current residence.
Confusing domicile with the State of Eligibility.
Assuming the address mentioned on the Aadhaar card determines the State of Eligibility.
Not checking the specific eligibility rules applicable to candidates who studied outside India or under special qualifying arrangements.
Candidates must fill out their “State of Eligibility” details in the correct place. This refers to the code of the State from which the candidate has passed the Class XII (or Equivalent) qualifying examination.
Important Points to Remember:
It is important to note that the State code of eligibility does NOT depend upon the native place or the place of residence of the candidate.
For example, if a candidate appears for the Class XII (or Equivalent) qualifying Examination from an Institution situated in New Delhi and is a resident of Noida, Uttar Pradesh, then the candidate’s State code of eligibility will be Delhi and NOT Uttar Pradesh.
An incorrect State of Eligibility may affect eligibility for Home State quota benefits during JoSAA counselling, wherever applicable. Candidates should follow the official rules rather than relying solely on their residential address.
2. Entering Incorrect Class 12 Qualifying Examination Details
Candidates must enter their academic information carefully and verify it against their official educational records before submitting the application form.
Incorrect qualifying examination details can create problems during document verification, counselling, or admission.
Common mistakes to avoid related to the qualifying exam details:
Selecting the wrong qualifying examination.
Choosing an incorrect board or university name.
Entering the wrong year of passing.
Selecting "Passed" instead of "Appearing", or vice versa.
Providing academic details that do not match official certificates or records.
Candidates appearing for Class 12 in 2027 should select the appropriate qualifying examination status and provide the information requested in the application form.
3. Selecting the Wrong Examination Paper or Paper Combination
Candidates should understand the differences between the three JEE Main examination papers before selecting their preferences.
The examination papers are the following:
Paper 1: BE/BTech
Paper 2A: BArch
Paper 2B: BPlanning
Candidates should select the paper or combination of papers based on the undergraduate programmes they wish to pursue and the relevant admission requirements.
Common mistakes to avoid related to the selection of JEE Main Paper:
Confusing Paper 1 (BE/BTech), Paper 2A (BArch), and Paper 2B (BPlanning).
Selecting an examination paper without checking the intended undergraduate programme.
Forgetting to select an additional paper when applying for multiple programmes.
Not checking the applicable examination fee for the selected paper combination.
Candidates can check the JEE Main 2027 exam overview to understand the examination pattern, available papers, and admission requirements.
4. Not Checking the Consistency of Details Across Documents
Candidates should ensure that the personal and academic information entered in the JEE Main application form is consistent with their official documents.
Differences between the application details and supporting documents can create problems during identity verification, counselling, or admission.
Common mistakes to avoid:
Entering a name or spelling that does not match official records.
Providing an incorrect date of birth.
Entering inconsistent parents' names.
Not reviewing automatically fetched identity information.
Providing incorrect category or academic details.
Candidates should carefully check the information retrieved through the applicable identity authentication system and follow NTA's instructions if they notice any discrepancies.
5. Ignoring the Difference Between Examination City Preference and Exam Centre
Candidates should understand that selecting an examination city preference does not guarantee allotment of a particular examination city or centre.
NTA allocates examination centres according to its applicable allotment rules and administrative requirements.
Candidates should select their examination city preferences carefully, considering travel convenience and the options available in the application form.
Common mistakes to avoid related to the exam city selection:
Assuming the first preferred examination city is guaranteed.
Selecting cities without considering travel arrangements.
Entering incorrect examination city preferences.
Confusing the preferred examination city with the actual examination centre address.
Note: The allotted examination city and the exact examination centre are communicated through the relevant official documents. Candidates should check their admit cards for their final examination centre details.
6. Not Checking the Fee Structure Before Selecting Examination Papers
Candidates should check the applicable JEE Main 2027 examination fee before completing the payment.
The examination fee varies depending on factors such as category, gender, examination centre location, and the number or combination of papers selected.
Common mistakes to avoid related to the exam fee:
Selecting an incorrect category, resulting in an incorrect fee calculation.
Not checking the fee applicable to multiple examination papers.
Confusing the regular examination fee with the additional late fee.
Not reviewing the payable amount before confirming the transaction.
For JEE Main 2027, NTA has provided a late application facility with an additional fee of ₹500 during the notified late registration periods.
Candidates should review the official fee structure before making payment.

7. Using an Inaccessible Email Address or Mobile Number
Candidates should provide an active mobile number and email address that they can access throughout the examination and admission process.
NTA uses registered contact details to communicate important application-related information and updates.
Common mistakes to avoid related to the address of communication:
Registering with an email address that is no longer accessible.
Providing an inactive mobile number.
Entering an incorrect email address or mobile number.
Not saving login credentials and application details for future reference.
Candidates should use their own accessible contact details or follow the specific contact information requirements mentioned by NTA.
8. Not Checking the Final Application Preview
Candidates must carefully review their JEE Main 2027 application form before final submission.
The application preview allows candidates to identify possible errors in their personal information, academic details, examination preferences, and uploaded documents.
Common mistakes to avoid:
Overlooking automatically populated information.
Missing errors in examination paper selection or city preferences.
Not reviewing uploaded photographs and documents.
Proceeding to fee payment without verifying the application details.
Candidates should also confirm that their uploaded files meet the document specifications mentioned in the official information bulletin.
9. Not Checking the Final Payment Status
Candidates must verify that their examination fee has been successfully paid and that the confirmation page has been generated.
They should not assume their JEE Main 2027 registration is complete simply because the amount has been deducted from their bank account.
Common mistakes to avoid related to the fee payment process:
Assuming that a deducted fee automatically confirms successful registration.
Not checking the payment status after completing the transaction.
Closing the payment process without verifying the result.
Failing to download and save the confirmation page.
Note: If the amount has been deducted but the confirmation page is not generated, candidates should follow NTA's payment-related instructions or contact the appropriate help desk rather than immediately making repeated payments.
10. Creating Multiple Application Numbers to Fix Registration Errors Without Understanding NTA's Rules
Candidates who make mistakes in their application forms should read NTA's instructions before submitting another application.
According to NTA's public notice dated October 30, 2026, candidates can submit a fresh JEE Main 2027 Session 1 application even if they have already generated an application number or paid the examination fee.
However, they must understand the conditions associated with submitting a fresh application.
Important Points to Remember:
New Application Number: Every fresh application generates a new application number.
Previous Fee: The examination fee paid for an earlier application will neither be refunded nor adjusted against the fresh application.
Valid Application: Only the latest application for which the examination fee has been successfully paid and the confirmation page generated will be considered valid.
Incomplete Fresh Application: If the fresh application remains incomplete, the earlier successfully completed application will remain valid.
Multiple Applications: Appearing or attempting to appear in the same examination session using more than one application number will be treated as an unfair means (UFM) practice.
Note: Merely possessing multiple application numbers is not considered an unfair means practice. However, candidates should consider using the correction facility when they only need to modify specific details.
11. Depending Entirely on the Correction Window
Candidates should not assume that every detail entered in the JEE Main 2027 application form can be modified during the correction window.
NTA specifies the editable fields, applicable conditions, and additional fees through its official correction instructions.
Common mistakes to avoid related to the application correction:
Assuming every application field can be edited.
Waiting until the last day to make corrections.
Not checking whether an additional correction fee applies.
Missing the correction deadline.
Assuming the correction facility will remain available after the announced dates.
Candidates should make every effort to submit accurate details initially rather than depending entirely on the correction facility.
