You're looking for a m:n relationship of objects. The relation between
students and tests shall have attributes (e.g. the grade). This
information doesn't concern one single student or one single test/exam,
but only the relationship between these two entities.

Get my diploma thesis about IRRE at the following URL:
http://typo3.org/uploads/media/Inline_Relational_Record_Editing.pdf

Read the chapter 3 to understand how IRRE could be used. The special
case you're looking for is mentioned in "3.3.3. Attributes for each m:n
relation". The kickstarter doesn't support IRRE yet, but hopefully will
soon. So you have to do this on your own or by copying the code parts
from the IRRE tutorial.

No. IRRE is a new feature that was first released with TYPO3 4.1. If you
want to use it, you have to upgrade your TYPO3 installation.
