Admission to an MSc program usually depends on specific academic criteria, but the score required can vary widely from one university to another and from one program to another. Most institutions look for a strong academic background and usually expect applicants to have a good undergraduate GPA or equivalent qualification in a relevant field. While some of these competitive programs set a rather high threshold for admission, others would be more flexible in terms of considering professional experience, research interests, and any other extracurricular activities. Still, a higher score will guarantee your position to be taken in one of the prestigious or highly competitive universities.
Beyond academic performance, MSc programs often entail other requirements such as entrance exams, letters of recommendation, and personal statements. Some universities also examine the research experience of the student, especially when the MSc course is purely research-oriented. If your first degree grades do not meet their expectations, highlighting other strengths within your application might compensate for your lower score, and it always pays to read the specific requirements for the specific program you have in mind.
