Dear Arvind,
I believe there are only Diploma courses which can be pursued after 10th. All degree programs needs a completion of 12th standard in mandatory. For Travel and Tourism I would suggest you to take up Arts in 11th and complete the course and then join for Degree in Travel and Tourism from a reputed college.

Your admission depends on your score in CMAT, MAT or CAT exam, not on your 10th or 12th scores.

You are eligible to become a cyber crime officer after your graduation with good marks and you should have knowledge of software architecture, ethical hacking and internet protocol configurations. After getting good stuff in respective domains only, you can be CCO.
