do you study hard the night before a test - and then forget everything by the next day? perhaps you could try ① using a voice recorder as well. studying out loud with a voice recorder is a good technique for testing yourself and building stronger memories. hearing things ② explained in your own voice can help you remember better because your ears reinforce ③ that your eyes have read and your brain has thought. if your book has sample test questions, you can record yourself reading ④ them and use the recordings as test rehearsals. and if you continue ⑤ to struggle with difficult concepts or long lists of hard-to-remember facts, just reading aloud and replaying your recordings can help a lot.
