Learn to code one small problem at a time.
From your first line of code to placement questions. Each problem is a little harder than the last, and the hints teach you instead of giving the answer.

Built to help you learn, not just to test you.
Most practice sites tell you "Wrong answer" and leave you there. Cintax shows you what went wrong and how to think about it.
See exactly which line is wrong
Your output and the expected output, line by line, with the wrong character marked. Compiler errors in C and C++ come with a plain-English note.
Hints in three steps, and a tutor that won't give the answer
Each hint goes one step further. The AI tutor points to where to look, so you still write the fix yourself.
The next problem matches your level
Every skill is a ladder of ten problems. Solve cleanly and you skip ahead; slip, and you get a little more practice first.
Pick a language. Start from zero.
Each course has seven stages, from printing your first line to the patterns behind placement questions. Each stage builds only on the ones before it.
Wherever you're starting from.
Start at the first stage, or jump to the one your class is on. You can always go back to earlier skills.
Never coded before
Start with one line that prints a message. The first problems take about a minute each, and nothing assumes you've seen code before.
Studying C, C++ or Python in college
Practise what your lab just covered: loops, arrays, pointers, functions. If your college uses Cintax, join with your teacher's class link and your practice counts for your class.
Preparing for placements
The last stages cover the patterns behind interview questions: two pointers, hashing, sliding windows, graphs and dynamic programming.
Teaching a programming class?
Give every student problems at their level, and see who is moving and who is stuck before the lab ends. Lab records and reports are ready when you need them.
