Hi Kaustubh,
You can apply for Bachelor's degree after your Diploma. Take your IELTS or TOEFL. You must take the SAT if you want to study in USA. Every university, country and program have different admission requirements. You must meet these and also have sufficient grades.

Hi Rishi,
Ideally, a PG Diploma is suitable. You can try for a Masters to universities not requiring 75%, there is no harm applying. IELTS of 6.5 with no section less than 6 is required for most PG level courses. Your SOP and LORs will also be checked.
