I started making flashcards for the Cold War (history) and I'm about a third of the way through with already 70 flashcards and I'm worried there will be too many. Keep in mind for history I was also planning on making flashcards for Whitechapel, Crime and Punishment, Civil Rights in USA, Vietnam War and Elizabethan period. Would it be worth it for me to carry on making flashcards? I'm doing them on quizlet btw.
