Dear candidate, it is totally worth it to waste an year and change your stream as stream taken in eleventh twelfth decide your stream of graduation and higher education and then jobs. Change your stream only if you are confident you can fetch marks in subjects of PCM and in higher studies.

It is just a myth created that there are no branch in electrical. If you are graduated from good college or you have done your graduation by studying properly then nothing can stop you to excel in your field of interest.

Hope, it helps!
