Rubberband and Exercise extensions in the classic notebook

Noteable notebooks (using the classic interface) come with the Rubber Band and Exercise & Exercise 2 extensions

These extension provide a mechanism to create a Question and Solution (or hint) system

THESE EXTENSIONS ARE COMPLETELY INDEPENDENT OF NBGRADER
(You can use them within an nbgrader assignment)

NOTE

Notebooks documents run with a notebook server that does not have these extension will just show the question and solution cells as normal cells

Rubberband

Rubberband is used to select a set of cells.

Note that you can select top-to-bottom, or bottom-to-top... the first cell, the question cell, is always the one nearest the top of the notebook document

Exercise

Having selected a set of cells, either click on the Exercise button (The exercise button), or use alt-s

This is the exercise in closed mode:
The exercise solution opened

This is the exercise in open mode:
The exercise solution closed

Exercise2

Having selected a set of cells, either click on the Exercise 2 button (The exercise2 button), or use alt-d

This is the exercise 2 in closed mode:
The exercise2 solution closed

This is the exercise 2 in open mode:
The exercise2 solution opened

Reminder

Whilst notebooks documents created with nbgrader do not required nbgrader to run, notebook documents using these extensions do require a notebook server with these extension installed.

Without the extensions installed, the question and solution cells are just normal cells
