Hey lavanya,

If you have forgotten to take a printout of the application form then dont panic. You can login into form through kcet website then take a printout provided you know your application number  and password. If you don't have your application number then go through your registered mail id or phone number, you wil fine it there. Or you can even find your application number through online transaction fees payment evidence or through the challan. If you have the challan copy then exclude the first character mentioned in "kea ref number" and write down the next 6 characters. That  happen to be your application number.

Hello Lavanya, the website of CET would have mailed you a soft copy of your admit card. Take a printout of that. if you are unable to recieve or find your admit card, mail the websites to resend your admit card and provide other possible details. all the very best!
