It is up to the university if they will give you the admissions. Admission decisions are not taken by the people outside of the university. Instead of asking if you will get admission find out how you can increase admission chances that will serve you better. Your grades are not too high but good to go with. Prepare a nice SOP outlining why you want to do Project Management and what are your plans related to your career. Reference letters from your teachers are also important. Visit the university website for exact details regarding admission information.
