A full-year course might be 1 credit; a semester course could be 0.5 credits. Universities sometimes ask how many credits a student has accumulated to confirm they\u2019ve completed a \u201cfull\u201d high school programme. For IB, IGCSE and CBSE, the word \u201ccredits\u201d may not be used formally, but you can usually <\/span><b>map<\/b><span style=\"font-weight: 400;\"> courses to credits when an online form demands it.
