Too risky?

I got 560/750 in PCM, I want to pursue Bsc (H) Physics, I’m keeping 10 colleges in my preference list

1. St Stephen’s
2. ⁠Miranda House
3. ⁠Hindu
4. ⁠Hansraj
5. ⁠KMC
6. ⁠Venky
7. ⁠Gargi
8. ⁠Ramjas
9. ⁠Daulat Ram
10. ⁠Khalsa

I honestly don’t want to add more but I am also scared of being too overconfident, what should I do😭
