Hello Reem ,

For doing MS, you must have 16 years of education right from your school till your degree.

Once you have completed your four year degree in BSc Medical Biochemistry and it makes upto total of 16 years of your education then you are eligible to apply for MS.

MS is a three year course that consists total of 6 semesters i.e 2 semesters per year.

Hope it helps.

Good Luck!
