Are these practice questions an official EHPLE paper?
No. The EHPLE is set and delivered only by the Federal Ministry of Health; these questions are an independent study aid written against the official Information Booklet blueprint and Ethiopian national clinical guidelines. The official examination is delivered in English as computer-based, four-option, single-best-answer MCQs, so the item format here matches the real assessment, but this bank is not an official past paper, a released item pool, or a simulation of the live testing environment. Always confirm registration dates, fees, and exam-day rules on moh.gov.et/ehple and hple.moh.gov.et.
