ArXiv:astro-ph/0112551 - Large-Scale Structure of the Universe and Cosmological Perturbation Theory, F. Bernardeau, S. Colombi, E. Gaztanaga, R. Scoccimarro - big paper
AstroPh:0602280 - George Ellis - Issues in the Philosophy of Cosmology - this is a proper scientific approach, i.e. serious philosophy explained in simple (scientific) words
calibration: lecturer should be able to do full exam in 60 minutes with a score of at least 4.5 (out of 5)
fixed day/time, expected up to 3 hours, allowed up to 5 hours, at KRA as in a traditional exam; repeat exam possible in September as in official program
exam uses a selection of wims exercises made available in exercise mode, i.e. the questions are different but statistically drawn from the same distribution in a multi-dimensional parameter space with N >> 1 parameters
same as for exercises: score rounded to nearest number in the set {0, 2, 3, 3.5, 4, 4.5, 5}
differences wrt exercises
stronger prerequisite relation between exercises - you must do the easier exercises before being allowed to try the harder ones
more severe scoring system: instead of
The examination for this subject requires verification that the students are working through examination questions using verifiable tools. Purely online methods of verifying the students' knowledge are insufficient for this course, so a face-to-face "traditional" exam is required. Experience has shown that some students use scientifically invalid methods.
exercise mode:
Scoring is enabled by default - but this doesn't count for any official zaliczenie!
Scoring is not limited by IP range - you can practice from Spain or Fiji if you wish.
link to wims: https://cosmo.torun.pl/wims - the exercise mode sheets have a warning in Polish ,,(bez zaliczenia!)" to remind you that your scores in exercise mode do not count officially

5.0 grade points on WIMS - how it's calculated
You can get a grade of up to a maximum of 5.0 points from WIMS exercises:
where
is the percentage done for a given "sheet" - let us normalise this to the range from 0.0 i 1.0
is the "quality" - in the range from 0.0 to 1.0; the power of 0.3 implies that the effect of is weak unless the "quality" parameter is very low

My scores
Global average: something out of 5. Here, something is your total amount of points
The formula for a single exercise done m times, is po m razy, gdzie , which is in the range from 0.0 to 1.0. This is a decaying average, with . In other words, the most recent tries at a realisation of an exercise have the most influence on the score for that exercise.
Chromium/Chrome bug: As of 2020 to 2024, chromium/chrome browser software has a bug that prevents the display of some of the exercises. Firefox is one browser without the bug.
