No syntax stumbles — focus on algorithmic thinking: conditionals, loops, arrays, functions. ▼ See code run, one step at a time Run your code and watch variables and arrays change step by step. The trace feature lets you visually follow why each answer is what it is. Same format as the actual Common Test — great for past-question practice. ▼ AI tutor guides your thinking Stuck?
