Chromosomes line up along the cell's equator, so it's metaphase.
An AI quiz generator turns your own study material into auto-graded practice questions. GoodOff finds the important ideas in a PDF, notes, lecture or web page, writes multiple-choice and open-ended questions, and explains each answer. Your score shows what to study next.
Retrieval practice makes you pull an answer from memory. Each attempt reveals a gap, each explanation repairs it, and the next attempt measures the progress.
