Use thick paper. When you build your flashcards, ensure you write them on thick cards or paper. You need to make sure you can’t see through the paper to get the answer on the other side.
If you are making your cards, be sure that they are all the same size. You don’t need completely different sizes of cards freely giving the answers. Otherwise, you aren’t memorizing the connection between the terms and explanations, but just what each size card says. That won’t be very helpful when you’re taking the test.
