Questions for first year linear algebra. From basics on vectors and matrices, via solving linear systems, inverse matrices and determinants, vector spaces, bases, linear maps, eigenvalues/eigenvectors, inner products.
In development: we're starting at the beginning :-) More questions will appear through the year 2020/21.

Combined the last two parts into one with some automatic fills of some of the gaps. Put the marks of the parts in.

Still need to adapt the marks per parts to make them a bit more round. Will do that once someone has tested that it works.

Saved a checkpoint:
Adapted the "introductory" Gaussian elimination question to include two cases: sometimes this one has a unique solution, and sometimes it has a free variable.
