Just wondering would it be best to read/memorise notes from other sources which have thorough notes, or would you just write from multiple sources and summarise yourself then memorise. l believe reading/memorising notes from which l do not have to write l just memorise. While if l write by the time l have finished that topic l would have most likely memorised 1/4 to 1/2 the topic. But just wondering what is your take on this, read or write your notes?
