If you were a PCMCS student (Physics, Chemistry, Maths, Computer Science) in 12th but your KCET admit card shows PCMB (Biology instead of CS), it could be due to a mistake while filling the application or a clerical error from the KEA side. First, check your application form to see what subjects you selected. If you chose the correct ones, it’s likely a KEA error. In that case, contact KCET authorities immediately for correction before the exam.

Hi aspirant,

It is normal , it was reported last year by many students because KEA issues admit cards with PCMB for all candidates regardless of whether they studied biology in PUC or not. Since you didn’t study biology in PUC, you don’t have to give a biology paper . Also, if you are applying for an engineering course, attending a biology paper won't give you benefit.

if you want excel you last month preparation for KCET you should cover this important topics.
