Is it necessary to have computer subject in 11th,12th for taking admission to UG courses like BCA Or is it easy for student with PCB stream
It not a compulsion to have a computer subject. However, you must have mathematics as your subject in 11th and 12th grade. I hope this answers your query! All the very best!

It is not necessary to have computer science in 11th,12th for taking admission in BCA Course anyone can take admission in that course, if you will learn and practice well the concepts well during your undergraduate than it will be easy for you to tackle the subject,at first you may be having some difficulties but after sometimes it will be okay as you will learn the concepts properly...

Feel free to ask more.

But you would have to see prospectus of each college to know whether they give admission to only PCM candidates or not.
For admission in btech in computer science or bachelor in computer application, you need to pass 10+2 with subjects physics, chemistry and mathematics.
It is good if you also have computer science with them but it is not necessary.
And PCB students are not eligible for this course.
Good luck...
