About this app

You can ask "Why is this the correct answer?" right then and there.

Yakupas is a past exam practice app equipped with "Pharmacist National Examination-Specific AI" designed by pharmacists. It utilizes a unique "National Examination Data Bank" compiled and analyzed from the 97th to 111th examinations (5,175 questions) as reference information. You can ask additional questions directly from the question screen about parts you don't understand even after reading the explanation, or why an option is incorrect.

■ From "Memorizing Answers" to "Understanding Reasons"
Typical past exam practice ends after reading the provided explanation.

Yakupas is where the real work begins. You can ask the AI ​​questions about any doubts that arise after reading the explanation.

• Why is this option incorrect?

• How can I distinguish between similar drugs?

• I'd like a simpler explanation of the mechanism of action.

• Ultimately, what should I memorize for the exam?

Even when studying alone and without someone to ask questions, you can move on to the next question without carrying over any unanswered questions.
