CBSE 10th

Starting from the point of view, hacking doesn't requires eligibility of academics. Hacking is just a skill which requires, Coding Knowledge, Network Knowledge, Server side Scripting Knowledge, Computer Hardware Knowledge and Testing Knowledge. Coming to the part, if you saw the articles, the children are around 5 - 11 years of age are hacking networks, finding zero day flaws in software etc. So this shows hacking doesn't require any academic courses. Learning hacking through any certification such as EC - Council CEH, (ISC) 2s CISSP, CISA and CISM from ISACA and OSCP from Offensive Security will improve the professional skills of hacking.

Hi,
If you want to study now, that's a good choice. Well, now, you are running your own business. I would suggest you to go for a business Diploma only. Apart from studies, it will also help you to grow your own business in a way. Or, you can do a Diploma in the kind of subject, where you will be taught about the products you are working with in your business. For example:
1 - If your business is apparel based (boutique, design house, apparel store), then you can go for a fashion designing course, or a fashion retail course or apparel designing or can be a textile related course.
2 - If it's a grocery or a general product based bussing, then you should go for a marketing course or consumer behavior studies.
Tell me what kind of business you are working in? maybe, then, I will help you in a better way, that what exactly you should go for.
Good luck!
