CTET

Yes, you can apply for the same. It is very good opportunity to fulfill your desires.

Since you have done B.Ed you are eligible to become a teacher in school.

I don't think reverse order of languages specified by you would create any problem, but I would recommend you to discuss with the CTET management once.

Yes, you can do it. But my suggestion is go for M.Tech in a respective stream by passing GATE out and which in turns provide you with an opportunity to enhance your teaching skills.

Yes, you can become a teacher in Kendriya Vidyalaya for PGT post, if you have a B TECH degree in Computer Science and more than 60% aggregate in it. Branches other than computer Science are not eligible for applying the post. For that, you have to look after the posts posted by Kendriya Vidyalaya Sanghatan. After clearing the exam conducted, you will be eligible to teach students of class 11th and class 12th subjects related to Computer Science. Note: One disadvantage for B.Tech student is that even if they are selected they will not be promoted further as they wouldn't have a B.Ed degree.

There are many central government vacancies and they can help you getting proper placements too.

Mainly, for appearing to CTET exam, you should have done some Diploma or Bachelor's degree in education. It is must. Then you can appear. Regards.
