CBSE 12th

Hello Pooja T, oh yes definitely. Provided of course you had taken PCB in 12th. There are plenty of students who take complete one year only for study of entrance exam like NEET or JEE Mains. Do not get disappointed by your rank of about 1L. What you should do is mediate and think as to what you want to become in life. Then go after it with full force. If you study exclusively for KCET for one year, I am sure that you can get much better ranking. Best wishes to you.

Hello Ashish Baghel, there are thousands of seats available pan India for CSE. But you can perhaps apply for only in your state or in GFTI across India based on JEE Mains results. If you are desirous of a particular institute then I suggest you to download the brochure of that institution for detail information.
Best wishes to you.

Hello Arul R, these days majority of states in India have decided that Diploma will be equivalent to 12th. If your state too has decided this, then you can take equivalence cert from the institution where you did your Diploma and then pursue any degree that you fancy. Best wishes to you.

Hello Shrushti Bankar,
These days, perhaps in Tamil Nadu, marks of 12th are utilised only to determine yes or no meaning minimum marks must be obtained in 12th below which a student can not seek admission in engineering. However actual admission is based on ranking in the entrance exam conducted by the states. Best wishes to you.
