How Many Days After Subject 3 Can You Take Subject 4?

After passing Subject 3, the timing for taking Subject 4 falls into three scenarios: taking it directly the same afternoon; within 9 days without an appointment—you can take Subject 4 within 9 days after passing Subject 3 by presenting your ID at the test center; or scheduling after 10 days, where success depends on the current number of test-takers, student priority, and temporary arrangements at the test center. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. It covers safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. Subject 4 Exam Notes: Exam Duration: The test lasts 45 minutes, and making 12 mistakes (6 questions) will terminate the session. Number of Questions: 50 questions are drawn proportionally from the Subject 4 question bank based on the type of license being tested, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions, featuring animation-based questions, image-based questions, scenario recognition questions, and text-based questions. Retake Notes: Failing Subject 4 only requires retaking Subject 4, arranged by the driving school without a limit on retakes. No additional fees are charged for retakes. Subject 4 Exam Tips: Strengthen weak areas by identifying reasons for mistakes. For marked questions, don't just memorize the correct answer—review regulations, textbooks, or reference materials to understand and internalize the reasoning. Categorize and summarize questions. Refer to the question bank's analysis to group similar questions, such as traffic signs for pedestrians, walking paths, and crosswalks, which are easily confused. Organizing them helps avoid errors. Use memorization techniques: Many questions involve numbers, so summarizing them can aid retention. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 4 is the colloquial term for the Subject 3 Safe and Civilized Driving Knowledge Test and is not a separate subject. Subject 1 covers road traffic laws, regulations, and related knowledge; Subject 2 assesses field driving skills; Subject 3 evaluates road driving skills and safe, civilized driving knowledge. The Safe and Civilized Driving Knowledge Test is conducted after Subject 3.

What Does ECU Flashing Mean?

ECU flashing refers to modifying the control program in the engine's ECU or completely rewriting the control program within the ECU. Every car engine has an ECU, which acts as the brain of the engine. The ECU collects information through various sensors and then controls the engine's operation via control mechanisms. This is why the ECU containing the control program is commonly called the engine control unit (ECU). The ECU is typically used in fuel-injected vehicles to control parameters such as fuel injection quantity and air-fuel mixture ratio. It consists of a microcontroller and peripheral circuits, where the microcontroller integrates a microprocessor, memory, and input/output interfaces on a single chip.
