Explore the pile
131 field notes cover biology ideas, explanations, recall questions, and ways to remember. Pull, bend, toss, and unfold a card.
A mountain worth
getting lost in.
Knowledge Mountain is a free public study space created by Raymon Su. Pull a note from the pile, follow a trail, and turn a moment of curiosity into something you remember.

Learning should feel approachable.
Our goal is to help students who feel overwhelmed find a small, useful place to start. The mountain offers both a surprising route through individual notes and a clear chapter-by-chapter path.
Follow the trail
Review chapters 1–19 in order, from the chemistry of life and cells through energy, genetics, evolution, and diversity.
Practice, then understand
Try multiple choice, matching, process ordering, true or false, written recall, flashcards, and memory aids. Read the explanations and learn from mistakes.
Search Anything
Look up biology words and processes, find related mountain lessons, and read live Wikipedia reference excerpts with source attribution. Continue exploring through NCBI Bookshelf, PubMed, and OpenStax textbook searches.
