What this is
Study is a library of study material, free and open to everyone. Pick a subject — budgeting, sleep, a vegetable garden, a pilot’s licence, a history paper — and work through it as cards or as a Challenge. Every question comes with its answer and the reasoning, and every subject shows the public pages it was written from — most answers link straight to the section.
No account, and nothing kept about what you study. It runs right in your browser.
97 subjects
Over 10,000 questions
Over 15,000 answers link to their source
One question, whole
The question. The options. The answer, said plainly. Why it is the answer. And where that is written down: every subject lists its sources, and most answers point to the very section — so you never have to take our word for it.
Personal Finance & Budgeting Basics
Answer: The FDIC's BankFind tool
BankFind is the FDIC's own lookup built for exactly this problem, letting anyone confirm whether a site claiming to be a bank is a genuinely insured institution before money changes hands.

How it is made
Every subject starts from pages anyone can read: an agency’s guidance, a standard, a vendor’s own documentation, a university extension service. Every subject lists the pages it was written from, and most answers link to the section itself.
Every question is reviewed before it goes up. Anything can still be wrong, which is why every subject shows its sources. Check what matters against the official material.
Where a subject has an awarding body — a licence, an exam — this is not its material and we are not affiliated with it. It is a companion to the official material, never a replacement.
