PurrLearn

PurrLearn is a free, bilingual (English / Chinese) learning site built around short interactive quizzes.

Its core is logical reasoning practice in the style of LSAT Logical Reasoning and GMAT Critical Reasoning: assumption questions, strengthen and weaken, flaw questions, and method of reasoning. Every question is written from scratch and every answer choice is explained, including why each trap is tempting. Official exam questions are copyrighted by LSAC and GMAC, so nothing here is copied from them — the arguments are original and follow the patterns the exams actually use.

This matters more than it used to: the LSAT dropped Logic Games in 2024 and replaced it with a second Logical Reasoning section, and the GMAT Focus edition removed Sentence Correction, leaving Critical Reasoning to split Verbal with Reading Comprehension. Both changes pushed weight toward argument analysis.

Alongside the exam-style drills there are gamified courses on thinking traps and cognitive biases, logic and reasoning, film and visual language, UX and design principles, psychology, and money and economics. Lessons are short, run in the browser, and switch between English and Chinese.

Free to use, with an optional Plus subscription that unlocks the advanced levels.
