FlowState coding practice
Get better at writing the next piece of code.
If you can follow what a coding tool just generated, but freeze when you have to decide what to write next, this is practice for that.
01 predict
What does this print?
a = 3 b = a + 2 print(b * 2)
Your answer
Choose an answer to see what the program prints.
02 trace
State at this step
n is now 1
n = 1
03 O.B.
World
O.B. moves north.
Who this is for
The three exercises on this page are the real work: guess what a program will print, step through the variables, then move O.B. on a grid. That is the same practice you get after you make an account.
A lot of people shipping software can read a file they did not write. The hard part is choosing what to build next, changing it on purpose, and debugging it when something breaks.
You do not have to stop using your tools. The point is to direct them, and to still be able to write code when you are on your own.
The eight skills
- 01RecognizeKnow the construct when you see it.
- 02PredictSay what it will do before running it.
- 03TraceFollow the state, step by step.
- 04ExplainSay why it works, not only that it does.
- 05ModifyChange its behaviour on purpose.
- 06ChooseKnow when it is the right construct.
- 07BuildWrite it from the problem, not from an example.
- 08CombinePut several together into something that works.
What is free
Free includes a diagnostic, your Reasoning Profile, a starting path, and a weekly practice budget. Pro raises the weekly limit and unlocks the rest of the catalogue. You are assessed the same way on both plans.
