What Is Inside the ZykoStudy Public Library? MCAT, Languages, Sciences and More

A library is only as useful as what is on the shelves. The ZykoStudy Public Library is built by students, so its contents follow what students are actually studying. Here is a tour of what was in it at the time of writing, in September 2026, with real examples of the kinds of sets you will find.

The size of the collection

There are more than 150 public sets holding close to 3,000 questions between them. The typical set has around 20 questions, and the largest reach about 70. Contributors number nearly 80, so it is not one person's collection, and that shows in the mix of subjects.

MCAT and pre-health content

One of the deepest areas is MCAT review. There are more than a dozen sets that break the exam into small topics instead of one giant deck, such as brain region functions, forces and torque in physics, sensation and perception, nucleophiles and electrophiles, periodic trends, gas exchange and pH regulation, and the immune system. Alongside them are anatomy and physiology sets on the musculoskeletal system, skin, blood, and the endocrine system, and a nursing style cardiac study guide.

Small topic sets are a good fit for the way memory works. Short, focused rounds that you return to over several days beat one marathon, which is the logic behind spaced repetition.

Intro sciences and social sciences

For anyone who just wants to review the basics, there are starter sets on cell biology, genetics and heredity, human body systems, and ecosystems, plus intro psychology (memory and learning, sleep and consciousness, research methods) and intro sociology (culture, socialization, deviance and social control). Some of these were written by hand as beginner friendly starting points. There are also chemistry sets on equilibrium, kinetics, and Le Chatelier's principle, and AP Environmental Science material.

History, geography, and social studies

History is well covered: World War II appears in several versions, along with the Industrial Revolution, the Mongol Empire, West African kingdoms, the Age of Exploration, the French Wars of Religion, and APUSH unit review. There are also sets on the five themes of geography and on world religions.

Languages and vocabulary

Language learners will find vocabulary and grammar sets in Dutch, German, Italian, Turkish, French, Chinese, and Spanish, including workplace vocabulary, pronunciation and common phrases, and verb conjugations. Some are written for students in other countries, for example Turkish literature and a Polish class quiz, so the library reflects more than one school system.

Math and practical or professional topics

• ›Math: factors and multiples, algebra, quadratics and complex numbers, calculus limits and derivatives, and elementary school placement practice.
• ›IT certification: several CompTIA Network+ sets, including exam objectives and network security.
• ›Business and other fields: management, outsourcing, tax law, marketing, architectural drafting, and computer architecture.

What to expect, honestly

Some sets have polished titles and some are named after the file they came from, and a few are just for fun. That is normal for a library made by its users. Preview a set first, and if you cannot find your subject, that gap is an opening: build the set and share it. The next student searching for it will be glad you did.
