Schools and colleges will usually look for at least five GCSEs (either NECO or WAEC), between A-D pass. Depending on what you want to study at university, English, maths and sometimes Economics (e.g., if you want to study Business Management) are often the essential subjects to study in your GCSE. While credit in C is the popular minimum requirement, higher WAEC or NECO grades (i.e., As and Bs) will leave you in a better position to apply for an A-Level.
