I want to pass N3 but I have been slacking lately (a rant post)

I will be taking the N3 exam this Sunday. However, I have been slacking on my Japanese studies for the past 2 months (May was kinda acceptable because I was too focused on helping my students, but June? no valid excuse, just plain lazy XD) I tried to study, but I get too sleepy, and even though I studied a bit before May, I feel like everything I learned at that time is now down the drain. I kinda regretted applying for July's exam instead of December, but I also think that it will just be the same no matter which exam date I choose. I have already accepted my 90% chance of failing the test lmao. But I will still do my best in the exam. How are you all, July test takers, preparing for the exam this weekend? With just one week left before the exam? Sorry for this post.
