CBSE Comprehensive Basic Science Exam, r, Spearman rank correlation coefficient. Anki user statistics that were not correlated with any of the exams were total days, days studied (% of total days), average interval (months), average ease (%), total flashcards, AnKing % young/learn/relearn, collection # young/learn/relearn/buried, collection # suspended/new, mature % correct, young % correct, and learning % correct. A mature card is defined as one that has an interval of 21 days or greater. An unseen/suspended/new card is defined as a card that has not been learned or seen. Retention rate is the percentage of cards correct in the young and mature phase. The collection is the total number of cards in users Anki profile
