Right people always think they are wrong, and wrong people always believe they are right. There is something about the mentality of someone who knows very little regarding a particular topic that makes them think they know everything. Oftentimes, those that are knowledgeable are often disregarded and doubtful of themselves.
This theme is frequently reinforced during debates on topics where people that are more concerned with winning start to disregard facts and target things that are meant to distract from the main issue.
Think about this as you study and take your exams.
Classes have been going on for four months now. At this point, you are likely the master of your craft and doubt your own capabilities, wondering what questions could be asked to stump you or what topics you don't know quite as well as the others. But there is only so much you can do to prepare for a test until you reach your endpoint.
Among my friend group, when we hit this endpoint, we have a tendency to say "the hay is in the barn". The knowledge is in your brain, you just have to use it.
If you truly don't believe you understand something, now is not the time to accept your fate! There is still time to reach out to your classmates or teacher and get clarification on a few final points before taking the test. If you identify a weak spot and fail to reinforce the material, you're going to feel silly when you see a question on the test that addresses that exact topic.
Prevent those moments and address your issues head-on. Improvement begins with acknowledging your shortfalls and working toward building a better understanding.
One of the best ways to reinforce learning is teaching the topic to other people. Being a teacher or a tutor constantly solidifies your knowledge as you learn to explain things in a variety of ways and answer questions from multiple perspectives. You never really know something until you can explain it in many different ways.
But there is an alternative side of this coin. If you are lying around, thinking you probably have a good enough understanding of the information, I encourage you to get up and reread it. There is no use in throwing away months of hard work because you don't want to study for one last test. Up until now, you have bent over backward and pushed yourself to the limit to do your best.
It's just one more week. A few more tests. Then slightly over a month to wind down and spend time for yourself or with those you love.
A time of recharging is right around the corner, but before you can recharge, you have to drain your battery. Take time for yourself, but make sure you aren't taking too much time to yourself. Self-care can turn into toxic behavior very quickly if you lose sight of the line between a break and procrastination.
Give these last few days all you got, and leave for break knowing you did your best.
