Questions
Is this cheating?
Zolviz shows you how a problem is solved, step by step, so you can do the next one yourself. It's a tutor, not an answer key. Use it to learn, not to copy.
What grade levels does it cover?
Middle school through first-year college: Pre-algebra to AP Calculus, AP Physics and AP Chemistry.
Does it work with handwritten problems?
Yes. Clear handwriting and textbook photos both work. If something is unreadable, Zolviz asks you to retake it.
How does the free trial work?
