Four gates,one retake each.

Nobody is pushed forward to protect a completion rate. If you miss a gate twice, you join the next cohort at that unit once, free.

How that shows in the numbers

Week 4

Four JavaScript problems in 3 hours, open book, no AI tools. Pass mark 75%.

closures, recursion, async

Week 8

Build a small React feature from a written ticket, with tests.

state, effects, TypeScript

Week 11

Add an endpoint and a migration to an unfamiliar codebase.

SQL, REST, auth

Week 14

Your team explains its code to two instructors for an hour.

design, trade-offs, reviews

From the week 4 assessment, problem 2 of 4.

A real gate question.

Write once(fn): it returns a function that calls fn the first time and returns that first result on every call after. Most students pass it on the first try after week 3.

function once(fn) {
  let done = false;
  let result;
  return (...args) => {
    if (!done) {
      result = fn(...args);
      done = true;
    }
    return result;
  };
}

const init = once(() => Math.random());
init() === init(); // true

Not sure you could write that yet? That is what the free prep course is for. Take the readiness check
