Admission to a postgraduate course like M.Sc. in Electronics without passing a specific entrance exam such as AP PGCET (Andhra Pradesh Post Graduate Common Entrance Test) depends on the admission policies of individual universities and colleges.

• Some universities and colleges offer direct admission to PG courses based on undergraduate academic performance. If you have a strong academic record in your bachelor's degree, you may be eligible for direct admission.

• Some institutions might conduct their entrance exams for PG admissions. You can apply to such universities and appear for their specific entrance tests.

• Certain colleges may offer merit-based admissions where they consider your undergraduate marks for the admissions.
