This is a very good product, so I highly recommend it to students who are interested. Step-up style! ◆3 STEPs◆ for smart preparation for the Common Test‼ ◆STEP 1. Analysis of the Common Test: Proposes study methods based on the analysis. ◆STEP 2. Training: Practice problems tailored to the exam questions. ◆STEP 3. Practice: Actual test in the format of the real exam, including the 2021 Common Test Main Exam (First Session). ★ Differences from the "Common Test Past Questions Study" (commonly known as the "Common Test Akahon") The "Common Test Akahon" is a "collection of past questions" that contains many past questions as they were. In contrast, "Smart Preparation" is a "focused preparation problem collection" by field, carefully selected with the best questions for Common Test preparation. It is ideal for those who find it difficult to jump straight into past question practice or who want to overcome their weaknesses.
