Waec Grade students with their best 6 subjects from three electives and 3 core subjects.
So the grading system is like this.
English + core maths + either social studies or inter science + any of your best 3 electives.
so your aggregate is C5 + B3 + A1 + B2 + B2 + B3 = English + core maths + social studies + econs + twi + either government or geography since both is B3.
So your total aggregate is the addition of the numbers. = 5 + 3 + 1 + 2 + 2 + 3 = 16
For nursing training, program you need to score an aggregate of 36 or better from your best 6 subjects. Clearly your aggregate 16 is far better than the 36 cut-off point they are looking for so you qualify to apply.
