Hello.

A candidate can appear in all three phases of AEEE 2021.  Candidates who want to appear for the Second / Third Phase of AEEE exam to improve their score need to register with paying INR 600. Hence, you cannot write all the three phases by paying for one. Candidates seeking admission should have an aggregate minimum of 75% in PCM with not less than 75% in Mathematics. The last date to fill the application forms for the first phase is 10th April 2021.

I hope this helps.
