[R] Any tests/exams freely available with answers to test basic R knowledge

[Daniel Brewer]

Hello,

I have the responsibility of ensuring that a colleague who is just
learning R knows the basics before a course where that is a requirement.
 The colleague has gone through a couple of tutorials so hopefully she
is ok, but I would like to give her a test to gauge it.

I was therefore wondering if anyone knew if there were any materials on
the web that would be suitable? and is possible had both questions and
answers.

Many thanks

Dan
