Hi Leon!
Studying smart is really simple thing to do. It helps boost your confidence, competence, and self-esteem, as well as reduce your anxiety about tests and deadlines. Such tactics you could use is studying in short chunks. This will allow you your brain process information much better, than obtaining lots of information in long sessions. Another method could be writing flash cards. This will help Your brain store the information better since you have written it down. You could also set study goals by tick them off once you complete them, or test yourself to see where you are at and what you might need to focus on. Lastly, active recall. This is known to be one of the best methods, by reading your flash cards and summaries out loud. This will help you retain the information in your long term memory. Ergo, by developing these effective study skills, it will give you the opportunity to cut down on the numbers of hours you spend while studying, which will leave you with more free time.
