Hello student i request you to please help me with the application you're concerned about as you've not mentioned the application name so that I'm unable to provide you the exact information about last date and process.

Yes Class 10th results are not declared yet but it's expected that it'll declare anytime soon in August.

Wait for the result or check if you can apply as an appearing Candidates and fill the application form.

Feel free to comment if you've any doubt

Good luck
