"Nurse National Examination Perfect! All 5 Choices! Prediction Problem Collection 5th Edition" Edited by Medical Friend Publishing Price: ¥1500 #MedicalFriendPublishing #Book #Nature/MedicalScience/Health Up to the first question on page 14, there are answer markings on the choices in orange ballpoint pen, but there are no markings after that. In terms of difficulty, I felt that these were probably questions with a low correct answer rate, even among general questions (based on my own experience). Thank you.
