do i get seat in b.pharmacy in second phase for 30k rank iam an sc candidate \

Dear student, for which exam are you referring to? The specific outcome depends on the state, the entrance exam taken (like AP EAMCET or others), the individual college's cutoff, and the number of available seats for the SC category in the second phase of counselling. Based on state-level exams, with a rank of 30,000, you might be able to make the cutoff in the SC category but again, it depends which exam/college you are referring to.
