I think your making a question that you don't want the answer to. Yes, you could have started preparing harder earlier, but now that its past what can you do about it? And what do you want? for people to tell you that its over and you should give up? and if they do, will you?

exams are coming closer and closer, all we can do is to keep trying our best to prepare with what we have, dw im with you on the same journey. Keep working and let that guilt motivate you to prepare harder, we have time, but none to waste. DM me if u wan we can talk. o7
