Can I Combine WAEC and NECO Results? Two Sittings Explained

By JAMB Advisor Editorial · 11 Nov 2026

Many candidates write both WAEC and NECO, or write a second exam to fix a missing credit. The natural question is whether you can combine the best credits from two results. The short answer: usually yes, but not always.

What "two sittings" means

A sitting is one examination — for example, WAEC May/June of one year. If you combine credits from two different examinations (WAEC + NECO, or WAEC school + WAEC private), you are using two sittings.

Most institutions accept a maximum of two sittings for admission. Three or more are generally not accepted.

When two sittings are accepted

For many courses — especially in arts, social sciences, management and many sciences — universities accept credits from two sittings, as long as all the required subjects are covered.

Example: For Economics you need English, Mathematics, Economics and two others. If your WAEC has English, Economics and Government, and your NECO has Mathematics and Geography, the combination may be acceptable.

When only one sitting is accepted

Some universities require one sitting for highly competitive courses, commonly Medicine and Surgery, Dentistry, Pharmacy and some other health courses. In that case, all five required credits must come from the same examination.

The rule is set by each institution. Always check your course and school in the JAMB brochure.

Two sittings in screening

Even when two sittings are accepted, some universities award fewer screening points to candidates using two sittings. If your school weights O'Level grades in its aggregate, a one-sitting result can give you an advantage.

How to combine results without problems

  1. Upload both results to JAMB. Both must be on your JAMB profile.
  2. Make sure your names match across both results, your NIN and your JAMB profile.
  3. Keep the original certificates or statements of result, and your exam scratch cards or result-checker tokens, for verification by the institution.
  4. Check the brochure for your specific course before relying on two sittings.

If you have a missing credit

If you are missing one credit for your course:

  • you can write another O'Level exam to cover it, provided two sittings are acceptable for your course;
  • or consider a course whose requirements your current results already meet.
