About SciolyPrep
SciolyPrep is a practice platform for Science Olympiad competitors. We help you turn study time into scored results with realistic practice tests for every event - generated instantly, graded automatically, and tracked over time so you can see exactly where you are improving.
How it works
AI Test Generator
Pick any event and difficulty - Invitational, Regional, State, or National - and get an original multiple-choice practice test in seconds. Every question is generated fresh, so you never memorize a fixed question bank.
Exam-Inspired Generator
We analyze the structure of real exams from the scioly.org Test Exchange - topic mix, question styles, difficulty curve - then write brand-new questions that follow the same format. No actual exam content is copied or reproduced.
Import Your Own PDFs
Upload any practice test PDF (or paste a Google Drive link) and we will extract the questions so you can take it online with a timer, automatic scoring, and full answer review.
Who it's for
Division B & C competitors who want extra reps beyond the official practice tests. Retake any test, compare scores, and watch your average climb.
Coaches and captains who need placement exams or topic-specific quizzes quickly - generate one, share it, and review team results together.
Self-studiers tackling a new event. Start at Invitational difficulty to build fundamentals, then work up to State and National level questions.
Event study guide
Short orientation for the most-practiced events on our platform. Each guide covers what the test emphasizes and how to practice it.
Anatomy and Physiology
Study the human body systems in depth. Each season focuses on different systems - practice identifying structures, explaining physiological processes, and interpreting clinical data.
Astronomy
Explore stellar evolution, galaxies, and deep-sky objects. Expect image-based identification questions, H-R diagram interpretation, and calculations involving luminosity and distance.
Botany
New for 2027 - plant biology across both divisions. Study plant structure and physiology, photosynthesis, reproduction and life cycles, plant diversity from mosses to angiosperms, hormones, and paleobotany.
Circuit Lab
Electricity and electronics - Ohm’s law, series and parallel circuits, power, capacitors, and electromagnetism. Includes hands-on multimeter and circuit-analysis tasks plus written problems.
Codebusters
Cryptanalysis of historical and modern ciphers - Caesar, Vigenère, Aristocrats, Morse, Baconian, and math-based ciphers up through RSA. Practice frequency analysis and timed decoding.
Crime Busters
Division B forensics - identify unknown powders, liquids, and fibers with simple chemical tests, read chromatograms and fingerprints, and use the results to solve a crime scenario.
Designer Genes
Division C genetics at full depth - Mendelian and non-Mendelian inheritance, pedigrees, gene regulation, biotechnology like PCR and CRISPR, and Hardy-Weinberg population genetics.
Chemistry Lab
Hands-on chemistry focused on periodic trends, reaction types, and lab technique. Practice balancing equations, predicting products, and analyzing experimental results.
Disease Detectives
Epidemiology in action - investigate disease outbreaks, study study-designs like cohort and case-control, and calculate measures such as relative risk and attack rates.
Dynamic Planet
Earth science with a rotating annual theme covering tectonics, oceans, or climate. Practice reading maps, cross-sections, and interpreting geologic data.
Ecology
Learn about ecosystems, energy flow, nutrient cycling, and population dynamics. Questions often feature food webs, biomes, and species interactions.
Experimental Design
Design and critique scientific experiments under time pressure. Practice identifying variables, writing hypotheses, and proposing controlled procedures.
Fermi Questions
Estimate answers to order-of-magnitude questions - from the number of piano tuners in Chicago to the weight of the ocean. Speed and reasoning matter more than precision.
Food Science
The 2027 season is all about dairy - milk composition, casein and whey proteins, freezing point depression, emulsification, pasteurization, and cultured products like yogurt and cheese. Practice the math behind the ice cream, curd, and butter lab tasks.
Forensics
Apply chemistry, biology, and physics to crime scene analysis. Practice identifying fibers, powders, fingerprints, and chromatography patterns.
Fossils
Identify fossil specimens and their geologic contexts. Know taxonomy, modes of life preservation, and major events in Earth history.
Heredity
Division B genetics - Punnett squares, inheritance patterns, pedigree analysis, chromosomes and karyotypes, plus the molecular basics of DNA, from replication to protein synthesis.
Machines
Physics of simple and compound machines - levers, pulleys, inclined planes. Practice calculating mechanical advantage, efficiency, and forces.
Meteorology
The 2027 focus is Severe Weather and Storms - thunderstorms, tornadoes, hurricanes, and winter storms - with heavy emphasis on reading weather maps, station models, radar, and other meteorological data.
Microbe Mission
Bacteria, viruses, fungi, and protists - their structure, reproduction, and roles in health and disease. Includes microscopy and staining techniques.
Optics
Geometric and physical optics - reflection, refraction, lenses, mirrors, and wave phenomena. Includes laser-shoot style problem solving.
Ornithology
Identify North American birds by sight and sound. Study anatomy, behavior, habitat, and conservation with a focus on the annual bird list.
Protein Modeling
Protein structure and folding - from amino acid chemistry through quaternary structure, plus visualization and modeling skills. The 2027 focus protein is the sialic acid binding site of the 2009 H1N1 influenza hemagglutinin.
Reach for the Stars
Introductory astronomy for Division B - stellar life cycles, galaxies, and space exploration. Practice with star charts and mission data.
Remote Sensing
Satellite imagery and Earth-observation data - the electromagnetic spectrum, sensor types, orbits, and image interpretation. Division C tasks in 2027 center on climate change processes.
Rocks and Minerals
Identify rock and mineral specimens using physical properties like hardness, cleavage, and luster. Understand rock cycles and formation environments.
Solar System
The 2027 focus is habitability within and beyond the Solar System - planets, moons and ocean worlds, small bodies, exoplanet detection, and what makes a world livable.
Tower
Build a lightweight wooden tower that holds maximum weight. Practice physics calculations, wood selection, and structural design trade-offs.
Water Quality
The 2027 focus is marine and estuary environments - water quality testing, macroinvertebrate bioindicators, estuary ecology, tides, and human impacts from eutrophication to ocean acidification.
Wind Power
Renewable energy engineering - blade design, turbine efficiency, and wind physics. Includes both build and written test components.
Write It Do It
Communication under pressure - one partner writes instructions for a structure, the other rebuilds it. Practice precise, unambiguous technical writing.
