**Technical English** is a qualifying section. You must score highly and pass this section during the exam series, or your remaining papers (Math and Mechanics) won't be evaluated. Use it to solidify your comprehension and report editing skills.

**Engineering Mathematics** and **Engineering Mechanics** are rank-determining sections. Your marks in these topics will determine your percentile and overall rank on the leaderboard.

**Classic Mode** features an active circular countdown timer based on question difficulty (Easy: 20s, Medium: 15s, Hard: 10s). If the timer runs out, the question automatically registers as incorrect. **Zen Mode** has no timer constraints—take as long as you need to calculate answers.

Your Mastery percentage represents the **highest percentage score** you have successfully achieved in a quiz for that specific category. For example, if you complete a Mathematics quiz and get 8 out of 10 correct, your mastery records as 80%. Retaking and scoring higher updates it.
