Hi there,

Competition is present in almost evey where in the world. Whichever course you opt there is some completion you have to face.

Since you have mentioned that which course have less completion,  several non conventional courses like Language corse, Tourism guide and many such other courses. Apart from this you can go for any courses but for that you must have skills enough to make anything possible without any issue. You can do a lot better if you think your competition is only you.

As such there are very low course that have comparative low completion problem but still you need to work on yourself for better reach and results.

In high competitive exams such as JEE mains and NEET only those who studied perfectly secured the seats. So simply it is must to focus on yourself.

Hope you understand.

Thank you:)
