Hello Srija,
Yes, after 10th you can join any good polytechnic college and do your diploma for 3 years. Engineering is a 4 year course but you will get 1 year relaxation if you are a diploma to degree student.
To get a CPL license first you need to get the SPL license.
SPL stands for Student Pilot License. It is the first step towards achieving your dream of obtaining Commercial or Private Pilot License! If you are interested in flying aircraft, you must apply for SPL.
While pursuing B.E/B.tech, you can surly join an aviation school and start with your flying. Both can be done simultaneously if you can manage both of them together. One can fly on weekends and attend the college during weekdays. You can pause your flying whenever you want to (during B.tech exams).
I would recommend that you should study for CPL exams before starting the flying as it would provide you more knowledge during practical training. Moreover you should be free from your exams before your flying completes.
I hope this helps you out.
