PhD Challenge

PhD Challenge is a quiz game that takes you from elementary school all the way to a PhD.

· 18 academic levels — Elementary, Middle School, High School, Undergraduate, Master's, and PhD — unlocked one by one · 6 graduation diplomas — 6th grade, 9th grade, 12th grade, senior year, Master's, and PhD. Pass each graduation exam to add the diploma to your Certificate Wall · Ability profile — see how you score across logical reasoning, data analysis, natural science, general knowledge and more, with an instant post-exam ability chart · Real exam conditions — each question has its own countdown (45–90 seconds); answers lock on submit and show an explanation, you can't go back, and the timer keeps running in the background · Fair retake system — 5 free attempts per level; once they're used, complete 8 hours of self-study to earn one free retake · Retake tickets — don't want to wait? Buy retake tickets for an instant retry, or get unlimited retakes forever · Stratified random questions — every exam draws a different mix, so memorizing answers won't get you through · Five languages: Simplified Chinese, Traditional Chinese, English, Japanese, and Korean · Fully playable offline; your progress is saved automatically on your device
