Best WAEC Subject Combination for Science Students: Choosing the right WAEC subject combination is one of the most important decisions every science student must make before registering for the West African Senior School Certificate Examination (WASSCE).
Many students focus only on passing WAEC but forget that the subjects they register for can determine the courses they are qualified to study in the university. A wrong subject combination can create problems during admission, even when a candidate has good grades.
Science students who plan to study courses such as Medicine, Engineering, Pharmacy, Nursing, Computer Science, Agriculture, or other science-related courses need to carefully select subjects that match their career goals.
For the 2027 WAEC examination, science students are expected to choose subjects that provide a strong foundation in mathematics, biological sciences, and physical sciences. WAEC requires candidates to register for a minimum of eight subjects and a maximum of nine subjects, depending on the approved examination requirements.
This guide explains the best WAEC subject combinations for science students in 2027, including the required subjects for popular science courses and important mistakes to avoid.
Why WAEC Subject Combination Is Important for Science Students
Your WAEC subject combination is more than just a list of subjects you will write during your examination. It affects your future academic opportunities.
Here are some reasons why choosing the right subjects matters:
1. It Determines University Admission Opportunities
Universities and other higher institutions have specific requirements for different courses.
For example:
