Yes you definitely can enter hotel management after completing your higher secondary studies. For the same you can join bachelors programme in Hospitality & Hotel Administration in IHMs present all over India, a BHMCT course in Lovely Professional University or BA (Hons) Hotel Management at IHM, Aurangabad. If you are interested in catering, etc., you can also explore BSc Hotel Management and Catering Operations courses. 

For all of these programmes, you can apply for them after passing Class 12. They are usually three to four year degree courses and selection process may include an entrance test or admissions can also be taken on the basis of 12 class marks only.
