About this app
For the Big Data Analyst written exam, how you review is more important than how many problems you solve.
DayPrep focuses on a learning flow that highlights your weaknesses and brings back problems you've already solved before you forget them. You can study seamlessly within a single app, from concept learning to over 4,900 self-created problems across 4 subjects, practice mock exams, error notes, and FSRS smart review.
[Key Features]
Concept Learning Tab
You can organize concepts before solving problems. The 41 chapters across 4 subjects are divided into 117 lessons; you can read through core concepts and then move directly to related problems.
Over 4,900 Self-Created Problems Across 4 Subjects
You can study the entire scope of Big Data Analysis Planning, Big Data Exploration, Big Data Modeling, and Big Data Result Interpretation, organized by subject and chapter. These problems were created in-house based on the publicly available official exam scope and learning objectives. Statistics and Modeling Calculations: The Process
For problems that require manual solving, such as sampling, test statistics, and model evaluation metrics, the app does not just provide the answer but shows the calculation process step by step. This allows you to pinpoint exactly where you made a mistake.
Engineering Calculator
For problems that cannot be solved using basic arithmetic, you can open the in-app engineering calculator to perform the calculation immediately. This allows you to continue solving the problem without leaving the screen.
Memorization Tips
Concepts and formulas that are easy to confuse are summarized in short memorization tips. Check them on the spot when you get stuck while solving a problem.
Answer Explanations and Detailed Option Analysis
Check the correct answer and key explanation for each problem. The detailed explanation allows you to examine key concepts and each option together, helping you understand why you were confused.
Problem Solving by Subject and Unit
Select the subjects and units you want to study. On the "All Problems" screen, you can use search, filters, and sorting to find the problems you need.
Start Diagnosis and Today's Recommendations
Initially, you check your current status with diagnostic questions. As your study history accumulates, the app guides you through recommended sets that reflect your weak subjects and problems to review. FSRS Smart Review
Adjusts review intervals for each question based on your memory status. Since it collects and displays questions due for review, you do not need to calculate your schedule manually.
Review Notifications
Notifies you of today's study and review at the set time. This helps you maintain a consistent study flow.
Weakness Heatmap and Question Frequency
Compares correct answer rates by subject and unit using color coding. You can identify weak areas and question frequency by unit, and jump directly to the relevant questions.
Incorrect Answer Notes and Questions to Review
Incorrect answers are automatically collected, and you can manually add specific questions to your review box. Leave your own notes for each question to review together during your next session.
10 Practice Mock Tests
Solve 80 questions across 4 subjects, tailored to the official exam format, in 120 minutes. Select any set of 10 to take, and check your results based on a minimum score of 40 points per subject and a total score of 60 points. Your highest score and test record are also managed. Learning Status and Continuous Study
On the Home screen, you can check the number of questions solved today, cumulative correct answer rate, progress by subject, and consecutive study days. You can also view your highest mock exam scores and study records.
Exam Schedule D-Day
Check the upcoming Big Data Analyst exam schedule and remaining days directly on the Home screen. You can also select the specific exam session you are preparing for.
Pre-Exam Checklist
