Hey.

Yes, candidates who are appearing in Class 12th boards in the present year are also eligible to appear for IMU CET in the same year. There will be options like Result awaited/ appearing this year which you need to select. The eligibility criteria laid out for IMUCET requires you to score a minimum aggregate of atleast more than 60% marks in PCM subjects in 12th boards to be eligible. But as your result is not out as of yet, your admission will be provisionally subject to you passing this eligibility criteria whenever your result is out. As of now you're very much eligibile to appear.

Best of luck
