hi,

as you have passed 12th course in 2019, that means you did not complete b.sc first year till now,  your code will be code 2, code 2 states that the candidate need to pass 10+2 course from a recognized education board with pcb  as a core subject and need to qualify the aggregate marks . you also need to have english as a subject in 10+2 course.

the qualifying marks criteria for general category is 50% marks in pcb in aggeregate, for sc/st/obc it is 40%, for pwd it is 45%.
