Class 11

Entrepreneurship will always have a scope ! It requires knowledge, skill, experience and practice. Commerce with entrepreneurship will make a great combo. But you need to continue the study/training in both into your graduation or maybe even into post graduation. Main commerce subjects are economics, accounting and business studies, they all get along well with entrepreneurship.
11th and 12th in these subjects will give you basic information on these, then you can graduate in either B.Com or BBA from top notch university like LPU. Both these degrees and the trainings within these at LPU can give you the in depth knowledge and great exposure to business. The entrepreneurship and community projects will help you gain the crucial hands on experience. Then there are innovation, design thinking and business incubation labs which will help you ideate, execute and even raise the funding for the business. So, effectively, 10+2 in these subjects will help but it is the practical trainings which can get you places in entrepreneurship.
Business is a team sport. Identify a sector to gain knowledge in. Although, I am actively advising small business over a large number of sectors.
