■ Everything to Study — Legal Summary · Basic Core Summary · Casebook

■ Practice — 1st Round Past Questions · 2nd Round Answers
· 1st Round Past Questions: Solve by year, subject, and theme, and review the explanations and relevant provisions for each question. Re-solve only the incorrect problems, or continue solving.
· 2nd Round Past Questions: View reference answers, explanations, and self-scoring points for each question.
· 2nd Round Answer Note: Where your paper answers pile up
Just like in an actual exam, take a photo of your written answers and save them for each question. As you rewrite the same question, your answers accumulate neatly.
You can retrieve your answers at any time, from your first attempt to your current one, and check how much you have improved by placing your first and most recent answers side-by-side in [My Past Answers].
Grade your answers alongside reference answers and self-scoring points, and your score changes are displayed as a graph.
(Photos are stored on your device. Before changing devices or deleting the app, back up to Settings › Photos & PDF Bundle. The app will notify you if you haven't backed up for a long time.)
· Answer Practice ALL IN — 6 types of 2nd Round answer practice; methods tailored to your subject and question type are unlocked.
- Paper Answer Sheet Photo (All Subjects): Take a picture of your written answers in your notebook and self-grade them side-by-side with the reference answers.
- Multiple Choice: First, check the conclusion, main point, and numbers of the question using a 5-option multiple-choice format. For each option, identify the reason for correctness (for calculation problems, identify the specific mistake and the recalculated formula for each incorrect answer).
- Numerical Answer Grading (Accounting & Tax Law Calculations): Enter the answers for each question for immediate grading. If you get it wrong, use the intermediate calculation value to identify where the error occurred.
- Handwriting (Tax Law Essay): Write your answers while timing yourself and compare the keyword inclusion rate with the reference answers — Tablet and keyboard recommended.
- Table of Contents Ordering (Tax Law): Practice the answer format by arranging mixed-up table of contents in the correct order.
- Fill-in-the-Blanks: Cover the keywords and answer numbers from the reference answers and fill them in. Level 2: Basic and Advanced (Article Number, Period, Intermediate Calculation Value).
Re-solve only the incorrect answers, gather and solve only the previously incorrect answers, and use the first letter hint.
Scores from practicing the same problems multiple times accumulate on a growth graph. · 2nd Round Study ALL IN: The study leader selects a question and posts it in the KakaoTalk room, where members write their own answers and exchange opinions. The process is conducted entirely via text messages, without the need for a server or membership registration.
You can submit photos of your handwritten answers in the same room, and we begin with warm-up exercises using past exam questions, including multiple-choice, fill-in-the-blank, and sentence ordering.
■ ALL IN’s Unique Study Tools — Bringing Scattered Studies Together
Store multiple PDFs of your textbooks, summaries, and workbooks, and study on your mobile phone, tablet, or Chromebook alongside past exam explanations, reference answers, and legal notes.
· Memo Notebook: Take notes directly in the box below each 1st and 2nd round question (it opens automatically if you get it wrong, and you can attach photos). You also write notes unrelated to the questions directly. Notes left here and there are gathered on a single screen in the Memo Notebook by subject and theme. You can search by keyword, organize by folder, and select only the ★ important notes or those you haven't reviewed yet.
· Final Wrap-up Bell ALL IN: Hang a bell in the places you will review right before the exam. From a single column for organization, number code cards, a specific article, key points from case law, and a single question from reference answers, to memos, photos, and PDFs. Swipe sideways in the item list to browse, view in full screen, mark as viewed, go through again, and solve collected first-round questions immediately.
· Photo Notes: Take photos of hand-organized notes, blackboards, and paper answers, and collect them by first and second rounds separately, organized into folders. Create self-made questions with hidden answers to mix and review, and add highlighter, ballpoint pen, or note-taking memos over photos, creating long notepads for each picture.
· Planning ALL IN: Create a daily routine (daily tasks) and drag it onto a calendar, and set up a book review plan (one book daily or multiple books alternately). Attaching app study to tasks, such as "20 past exam questions" or "1 second-round answer," automatically checks them off after completion, and postpones backlogged tasks all at once. Includes a stopwatch for pure study time and daily study reminders.
**From a single column for organization to a single task, to a single set of notes, to a daily study reminder, to key points from case law, to a single reference answer.** · Scanned PDF: Take notes on PDFs of textbooks and summaries using a highlighter, ballpoint pen, or notes.
- [Find in My Textbooks] in Questions: Search your textbooks by themes, keywords, or provisions from the first round of questions and second round reference answers, and open the relevant page immediately.
