Learn works fine in v7. It just needs to be properly installed. The command is there already, so you may not need to follow all of the steps below, but it doesn't hurt:

I did this as root, but it could possibly be done as another user, I'm not sure.
cd /usr/src/cmd/learn
make
make lessons
make play; make log
That's it. make will complain about missing files that it tries to delete, but these can be safely ignored, since make then creates them anyway.

Here's the result run as a normal user:
$ learn
These are the available courses -
  files
  editor
  morefiles
  macros
  eqn
  C
If you want more information about the courses,
or if you have never used 'learn' before,
type 'return'; otherwise type the name of
the course you want, followed by 'return'.
macros
If you were in the middle of this subject
and want to start where you left off, type
the last lesson number the computer printed.
To start at the beginning, just hit return.

This script deals with the use of the "-ms" macro
package to produce Bell Laboratories style documents.
Before trying it, you should be familiar with the
editor.  To test that, please enter the file
typed below, exactly as is, into file "decl".  Then
type "ready".

.PP

Good.  Lesson 1.1a (1)

When you have some document typed in "-ms" style,
you run it off on your terminal by saying:

  nroff -ms file

where "file" is the name of the file it is on.  For example,
the file "decl" in this directory is in a suitable format
for running off this way.  Do so.  Then type "ready".
$
Interrupt.
