No sign-up needed. Here is a real task with a real bug in it. See if you can get the nudge to give you the answer.

Python · GCSE

Times table

Ask the user for a number, then print its times table from 1 to 12.

You have got it when

Takes input from the user
Uses a loop, not 12 print statements
It prints all twelve rows

Three nudges available. None of them will write the code for you.

2Pick where to start Year 7 to 9 if you are new to it, GCSE if you are working towards the exam.

3Tell me what is wrong with it This is early. If a hint is confusing or a task is badly worded, I want to hear it.

E-learning

Coming soon

Short videos that walk through a topic before you attempt it, so you are not reading a wall of text at eleven at night.

Count-controlled loops: why range stops one short0:15

One idea per videoFour to six minutes on a single thing, not an hour on a whole unit.
The same voice as the hintsRecorded by me, from the lessons that worked in class.
Watch, then do itEvery video sits next to the task it prepares you for.
Exam technique tooHow to read a question, and where the marks actually get lost.

Coming very soon, and free like everything else. Join the list and you will get them the moment they are up.

Hi, I'm Mr Ismail

I teach secondary Computer Science.

Students genuinely want to learn to code. The problem is what they reach for when they get stuck. AI assistants are built into terminals and code editors now, and every one of them is designed to hand over the finished answer. You end up with working code and no idea why it works.

So I built my own. It tutors instead of solving. Three levels of hint that point you at your mistake without ever writing it for you, worked examples explained a line at a time, and exam-style quizzes to check it actually went in.

More topics and more exam boards are coming. It's free for students, and it stays free, because that was the whole point.
