## What is Introductory Biology Tutor?

Learn introductory biology by connecting mechanisms, evidence, and systems—not by memorizing isolated terms.

Introductory Biology Tutor is a complete Biology I learning companion designed for college students, AP/IB learners, pre-health students, and anyone who wants a clearer way to understand cells, genetics, molecular biology, metabolism, and experimental reasoning.

BUILD UNDERSTANDING, THEN APPLY IT

Work through 18 connected course areas and 96 guided lessons that move from core ideas to biological mechanisms, misconceptions, and application. Lessons are designed to help you understand why a process works before asking you to use it.

PRACTICE WITH REASONING, NOT JUST RECALL

Test your understanding with 768 questions covering concepts, mechanisms, experimental design, quantitative reasoning, data interpretation, and transfer. Visual questions use diagrams, gradients, chromosomes, pathways, experimental setups, and molecular evidence to make the biology easier to reason through.

When an answer is wrong, the app explains why the choice breaks down and gives you another chance to reason to the correct answer.

EXPLORE BIOLOGY INTERACTIVELY

Use 16 interactive Explore tools to work with biological systems directly, including:

• Genetics Workbench
• Cell Explorer
• Membrane Transport Lab
• Metabolism Explorer
• Cell Signaling Explorer
• Meiosis Explorer
• DNA Replication Explorer
• Gene Expression Explorer
• Gene Regulation Explorer
• Biotechnology & Genomics Lab
• Development Explorer

TRACK WHAT YOU ACTUALLY KNOW

Progress tools show course coverage, first-try accuracy, weak areas, saved questions, and what to review next. Review Center helps you return to concepts that need attention, while Exam Review combines material across the course for cumulative practice.

A COMPLETE BIOLOGY I COURSE

Topics include foundations of biology, chemistry of life, biological macromolecules, cell structure and function, membranes and transport, enzymes and metabolism, cellular respiration, photosynthesis, cell communication, mitosis, meiosis, Mendelian genetics, chromosomal genetics, DNA replication, gene expression, gene regulation, viruses, biotechnology, genomics, and development.

Built for students who want biology to make sense as a connected system.

No account required. Your learning progress stays on your device.
