Biochemistry that actually clicks. Figure-first lectures and practice that grades itself, across three full courses.
Three courses
Pick your bench.
Each course opens to its lecture library and a self-grading practice bank.
BCH 100 · Introductory Biochemistry
Water, amino acids, enzymes, carbohydrates, bioenergetics, glycolysis, respiration, photosynthesis, lipids, signaling, nitrogen.
Metabolic & Endocrine Biochemistry · BCH 120
Hormone signaling, the pituitary axis, thyroid, catecholamines, gut & body mass, diabetes, steroids, calcium, cortisol, eicosanoids, growth, reproduction.
Advanced Human Biochemistry · BCH 130
The clinical sequel: metabolic syndrome, diabetes, dyslipidemia & atherosclerosis, GI-hormone disorders, hormone-dependent cancers, reproductive & menopausal endocrinology, bone, adrenal & fluid balance, eicosanoids, pregnancy.
Three ways to practice
Pick how you want to study.
Every course opens the same study app with three modes. Choose a course, then jump straight into any mode.
Test
Pick a difficulty on the metabolic-state ladder, beat the clock, and get a score. Written answers are graded for you; land your result on the leaderboard.
Start a test → ✏️Practice
One question at a time, no clock. Numeric answers check the moment you enter them; written and drawing prompts reveal a worked model answer.
Practice freely → 📖Learn
Browse every question with its full solution already worked out, unit by unit. Read it through first, then switch to Practice or Test.
Open Learn →What you can do here
A whole study toolkit in one pond.
Not just slides to read. Everything below is built in and ready the moment you open a course.
Three study modes
Learn to read solutions, Practice with instant feedback, or Test yourself against the clock. Switch any time.
It grades itself
No multiple choice. Numeric problems check your exact answer live; written answers get graded against a rubric with a worked model answer to compare.
A difficulty ladder
Test mode climbs a metabolic-state ladder, from Fed through Starvation to Ketoacidosis, that weights the question mix and the clock to match.
Jump to the slide
Every practice question links straight to the exact lecture slide it came from, so you can review the concept in one tap.
Score & leaderboard
Track your personal best and post a test score to a shared class leaderboard for a little friendly pressure.
Take the slides with you
Read any lecture in the browser, or download the full deck as a PDF or PowerPoint to study offline.
Figure-first lectures
Every pathway, curve, and molecule is drawn from scratch and sized to read from the back row, not a blurry textbook scan.
Clinical throughout
Real cases like Cushing's, diabetes, Graves', and gout tie the chemistry back to the body and the clinic.
