's certainly frustrating when you encounter issues while trying to download your admit card, especially with the exam approaching. Here's what you can do right now if your PCM (presumably Physics, Chemistry, Mathematics for JEE Main) admit card download is showing an "invalid email ID" error:

Immediate Actions:

1. Double-Check the Entered Email ID:

   • Carefully re-examine the email ID you are entering. Ensure there are no typos, extra spaces, or incorrect capitalization. It needs to be exactly the same as the one you used during the JEE Main registration.
   • Try entering it manually instead of relying on autofill, which can sometimes introduce errors.

2. Try Other Login Credentials:

   • The JEE Main portal usually offers multiple ways to log in. If you are using your email ID, try logging in using your Application Number and Password or Application Number and Date of Birth . You should have received your application number during the registration process (likely in a confirmation email or SMS).

3. Check for "Forgot Password" or "Forgot Application Number" Options:

   • If you suspect you might have forgotten your password or are unsure about your application number, look for the "Forgot Password" or "Forgot Application Number" links on the admit card download portal. Follow the instructions to recover these details. They will likely send the information to your registered mobile number or email ID (the correct one).

4. Verify Your Email Inbox and Spam/Junk Folders:

   • Even if you think you are entering the correct email ID, there's a slight chance the NTA might have sent some communication regarding your admit card or login issues to your registered email address. Check all folders, including spam and junk.

5. Ensure Stable Internet Connection:

   • A weak or unstable internet connection can sometimes cause issues with website interactions. Make sure you have a stable and good internet connection before attempting to download again.

6. Try a Different Browser or Device:

   • Sometimes, browser-specific issues can occur. Try accessing the admit card portal using a different web browser (e.g., Chrome, Firefox, Edge, Safari). You could also try using a different computer or mobile device.

7. Wait and Try Again Later:

   • The servers might be experiencing heavy traffic, especially close to the admit card release or exam dates. Wait for some time (e.g., an hour or two, or try during off-peak hours like late night or early morning) and then try downloading again.

If the problem persists after trying the above steps, here's what you should do immediately:

8. Contact the NTA Helpdesk: This is the most crucial step if you are still unable to download your admit card. The National Testing Agency (NTA) has a dedicated helpdesk to assist candidates with such issues. You can reach them through the following means (as per the information available):
