Hi Juha
Going back to your original post asking about options - you might also consider NUMBAS. This is open source project lets you create write questions (or browse/edit from a large public question bank) - you then download an exam package as a SCORM object activity that you can put into Moodle for students to attempt.

Here is a quick comparison compared of NUMBAS to the other built-in Moodle maths Quiz questions and STACK question type. This is off the top of my head (sorry it's not well ordered and it's just an opinion and not definitive/comprehensive by any means (especially subjective comments I've indicated with an asterisk *)!
| Feature | Moodle Quiz Activity - maths question types | STACK question type | NUMBAS |
|---|---|---|---|
| Support error carried forward marking (incorrect previous answer can be used later for credit) | No | Yes | Yes |
| Support for units | Yes (although a little clunky*) | Yes | Yes |
| Support for algebraic expressions | No (string matching only) | Yes | Yes |
| Support for randomised question variables | Yes (creates multiple copies of a question). Question variants appear in the same order in the Quiz and can't be shuffled (as each question variant need to be organised into a category). |
Yes | Yes |
| Support for adding worked solution feedback with the random question variables | No (although this could be added programmatically via GIFT import) | Yes | Yes |
| Reporting |
Yes | Yes | Limited (SCORM reports are unpleasant to read) |
| Regrading | Yes | Yes | No (actually, this is possible if you host questions on server and link via LTI, but not via the simple SCORM activity route) |
| Writing questions* | Easiest* | Hardest (uses maxima syntax) Public question banks are available (e.g. Domain)* |
Tricky* (uses JME syntax) Questions are written on numbas.mathcentre.ac.uk (need to create a free account) - where you can browse other peoples' questions |
| Writing custom feedback based on student response | Limited | Yes | Yes, but somewhat tricky at the moment*! |
