About this app
DayPrep’s learning features for dietitians are available for free.
We have captured the entire flow of preparing for the National Dietitian Examination in a single app. Solve a question bank of 2,200 questions across four subjects—ranging from Nutrition and Biochemistry to Food Service, Hygiene, and Related Regulations—and check your learning progress with 10 full sets of practice mock exams. By linking subject-specific solutions, error management, FSRS smart review, and weakness analysis, you can continue your preparation for the National Dietitian Examination. Initially, you can verify your current familiar scope through subject-specific solutions, and later, continue your study focusing on incorrect answers and questions to review. As the exam approaches, organize your preparation flow by checking mock exams and the exam D-day together. After solving problems, review confusing options through answer explanations and detailed answer choice analysis, and save important notes to refer to during your next review. You can track your learning progress through subject-specific progress and cumulative correct answer rates, allowing you to identify weaknesses that change during your preparation. Select the features you need and utilize them according to your learning style.

Question Bank of 2,200 Questions Across 4 Subjects
Learn through questions covering four subjects: Nutrition and Biochemistry, Nutrition Education, Dietetics and Physiology, Food Science and Cooking Principles, Food Service, and Hygiene and Related Regulations. You can select a subject to start solving problems, and on the full question screen, you can continue solving problems without being restricted by the scope. Manage the subject-specific study flow necessary for the Dietitian certification exam in one place.
10 Sets of Practice Mock Exams
Check your practical exam skills by taking mock exams based on the question count and time structure of the actual National Dietitian Examination. With a total of 220 multiple-choice questions (5 options), you can practice the flow of the first session (120 questions in 100 minutes) and the second session (100 questions in 85 minutes). After solving the problems, check your results against the passing criteria of achieving a total score of 60% or higher and a score of 40% or higher in each subject.
Answer Explanations and Detailed Option Analysis
Conclude your study by reviewing the correct answer and key explanation for each question. Through detailed answer choice analysis, you can review the reasons for your correct answers and the options you found confusing. Instead of simply checking the correct answer and moving on, you can reorganize the judgments needed for the next question.
**Problem Solving by Subject and Full Question Screen**
Directly select the subjects you wish to study to start with the necessary scope. The full question screen allows you to view questions from multiple subjects in a single flow. Solve the question bank just as you would review a dietitian workbook, and adjust the scope of your practice according to your daily study plan.
**FSRS Smart Review**
Manage review times for each question using the FSRS interval repetition method. It collects and displays questions that are likely to fade, reducing the time spent selecting which questions to review next. By maintaining a review flow based on your solution records, you can steadily build your preparation for the dietitian exam.
**Incorrect Answer Note, Questions to Review, and Memos**
You can collect incorrect answers in the incorrect answer note to review them again. Save important questions as "Questions to Review" and record the reasons for confusion or details to check next in the question-specific memos. You can review solutions and records together without separating them. Weakness Heatmap and Home Study Status
Identify areas for improvement using the Weakness Heatmap, which displays correct answer rates by subject and unit using color coding. On the Home screen, you can view today's completed problems, cumulative correct answer rates, progress by subject, and consecutive study days at a glance. Use this to determine which subjects to solve more of and to plan your next study session.
Question Frequency Analysis (Premium)
Check the frequency of questions for each unit within each subject. You can examine the weight of each unit when determining your study order. Organize the areas to focus on to align with your National Dietitian Examination preparation schedule.
Exam D-Day and Checklist
Select the exam session you are preparing for to view the remaining days until the exam. Use the checklist to review items to prepare before the exam. Manage your study progress and exam preparation within the same screen flow.
Light/Dark Themes and Offline Study
You can follow system settings or select your preferred Light or Dark theme. Question data is stored on your device, allowing you to continue solving problems and reviewing even in locations with unstable internet connections. Continue studying for the National Dietitian Examination based on your location and connection status. Guest Start and Device Sync
You can start studying immediately as a guest without signing up. When you log in, your study history, review schedule, incorrect answer notes, and individual question notes are synced to your account. You can check the problems you left off and your study history even if you switch devices.
[Recommended for These Users]
This is suitable for those preparing for the National Dietitian Examination for the first time who want to start by solving problems by subject. Those retaking the exam who wish to organize their previous mistakes and weaknesses can also utilize the study records. It is also helpful for those who want to review major subject content and check their skills using question banks and mock exams tailored to the dietitian certification exam format. You can establish a study flow by solving subject-specific problems during short breaks and continuing with incorrect answer notes and FSRS reviews on days when you have more time. When you are unsure which subject to start with, you can determine the next scope of practice by looking at the subject progress and weakness heatmap on the home screen. By repeating practice, you can check your cumulative correct answer rate and consecutive study days to maintain a study rhythm that suits you.
