Yes, you can apply for CPL course in Dean International Flight School after class 12th, if you had science along with physics plus maths.

If you are not interested in B.Tech then you should go for BA if you want to become an IAS Officer.

If you're interested in BHM after 12th, you can directly approach the college for seats and write the entrance exam. Few colleges have entrance exams and few don't have any such entrance exam. You can directly apply in that case. If you're looking for a reputed institution and a good life in the hotel industry and a better experience, I would suggest you to take up NCHMCT-JEE, it will help you get through all the hurdles easily.
But you need to be prepared in advance for the entrance exam and apply for it before date.
