Alternate examinations that may be used by your college or university for credit (and a grade) in this course will be available from Wikiversity by courier for closed, proctored session testing of proficiency.

Hypotheses[edit | edit source]

  1. By subpaging as many of the lectures in this course as possible under radiation astronomy the overall popularity of the course, or lecture set, can be compared with other lecture sets here at Wikiversity.
