To be offered conditional admission you would need to first apply and pay the non-refundable application fee, have a TOEFL/IELTS score within the conditional range, and be recommended for acceptance by the program.  Not all programs offer conditional admission, and some may require higher English language test scores so you will want to contact the program you are applying to and see if that is an option.  You can find more information on conditional admission on the Graduate School's International Admissions Requirements page
