I've passed 12th commerce. I am interested in hacking line. Which course is better after +2 (commerce) for hacking?

If you want to get into hacking line then first understand the concepts of networking. For networking you can go for CCNA Cisco certified Network associate! After that you can go for CEH- Certified ethical hacking which is the most basic course and the first path to get into hacking. Good Luck.

Please pursue law and do specialisation in cyber crime. This will surely help you. Prepare for CLAT exam to get a good college.
