# Joining a class and submitting work

The code, the assignment list, and the Submit button in the editor.

## Joining

Your teacher gives you a six-character code. Go to /class, type it in
and press the button. That is the whole thing.

The code is upper case and has no O, I, L, 0 or 1 in it, so if you are looking
at something that could be a letter O it is a zero, and it is not.

You need an account to join a class, because a class is a roster and a roster
needs names. You do not need one to use Mokxi: the simulator works signed
out and always will. See signing in.

## Your class page

/class/<id> lists the work your teacher has assigned: each assignment with
its title, its due date if it has one, and an Open button.

Opening one puts you in the editor with the circuit or the lesson already
loaded.

## Parts that will not move

Some assignments come with part of the circuit held in place. A held part wears a
small padlock, a held wire is drawn a shade back, and the cursor over either one
is a no-drop. Select one and the properties panel shows its fields switched off
over a line saying Locked. Only the person who set this work can unlock it.

That is on purpose, and it is only the starter. You can still do everything the
work asks of you: add parts, wire into a locked part's pins, name nets, change
anything you added, run it and read all of it.

Sometimes the code is held too. The file strip says Locked by whoever set this
work. You can read it and run it.

Copying a locked part gives you one of your own. A copy is yours, so it pastes
unlocked. Forking the assignment into your own project does not unlock it: the
copy is the same work, and owning it is not being the person who set it. Ask
your teacher if something is held that should not be.

## Submitting work

Build the thing, then open the Save menu in the editor's header. With an
assignment open there is one extra item in it, and pressing that submits the saved
project to the class.

You can submit again. The latest one is what your teacher sees.

For a lesson, your progress goes with it, so passing seven of nine steps shows
as seven of nine rather than as nothing.

## Checking your own work

Some work is set with checks on it: things your teacher expects your circuit
to do, written once and run on everybody's. Where there are any, your class page
has a Check my work button under that piece of work.

Pressing it runs your own circuit, here in your browser, on the same simulator
the editor uses, and tells you how each check went with the number it measured
beside the number that was wanted: it toggled every 1462 ms; expected every
1000 ms, within 50. That is a thing you can go and fix. You can press it as
often as you like, and what it finds goes to your teacher with your submission, so
they see what you saw.

It is grading the simulation, which is not a bench: the timing is ideal and
there is no analog noise, and the panel says so. And it never shows you your
teacher's circuit or anybody else's, only your own.

## What your teacher can see

The work you submitted to that class, and how far through a lesson you got.

Not your other projects. A project is private when you make it and stays private
until you make it public, whether or not you are in a class.

## Leaving

Leave this class on the class page. Your own projects stay in your account.
The submissions you made to that class do not.

## Getting your work out

Any project saves to a file and opens again anywhere, with no account. That is
worth doing at the end of a course, so what you built does not depend on a class
you are no longer in.

## Earning something for it

Passing a lesson step earns XP, and the steps the simulator actually checks are
worth more than the ones you tick. See
XP and levels and
streaks and badges. Joining a class is itself
a badge.
