Hi , 

So the number of seats in sls Hyderabad are : 

BA LLB(Hons)-120

BBA LLB(Hons)-120

After the admissions are done for the reserved category seats and such others , there will only very few seats left . Competition would be high . So with a rank of 631 in the waiting list , the chances of getting admission are bleak .
