Nahi, nahi, mujhe bhi lagta hai ki wo Karan ho sakta hai, and not Balli.
Especially because Dhanu thought, 'Ab in mein se Karan kaun hai aur Balli kaun?' insinuating that they couldn't differentiate between them either.
It could be that Karan was the one who drove off and then Balli chased him, but instead of Karan being the one unconscious, he knocks him out and places him in there, taking Balli's place.
The reason he acts weird is because he WANTS everyone to get suspicious and things to act naturally (Dhanu probably won't believe that no one gets even a bit suspicious), but he can't tell them because he knows Dhanu's people can be watching, and he has an elaborate plan going up.
OR Karan and Balli have a talk and Balli agrees to help Karan (for whatever reason) and it's actually Balli that goes in the academy and Karan that goes with the terrorists but they are on the same side, meaning Balli will help Karan spy and take the information.
OR it could really just take the conventional way and have Balli in the academy like they show and Karan with the terrorists as they show...
