Hi,
Please complete your 10+2 with good grades, first class preferably. Take the SAT and TOEFL to be considered for admissions into Bachelor's degree programs. Whether you are from SC/ST, it does not matter in the US. Quota system exists only in India. Admissions abroad are purely on merit so complete and focus on your studies.

Hi Dhruvil,
This will depend on the university and your previous Diploma. They will check if you have met the credit point requirements and will accordingly decide. You must email your academic profile to some colleges abroad for this.

According to me, US would be much better than Germany in many aspects.
