I'm feeling quite the same Visionz. I am generally a motivated student, sometimes even enjoying a nice spot of study, in certain subjects, but recently i've been fading. I'm pretty sure it's just the idea of homework that gets me down, not the study itself. Once i get started i'm fine but initiating a good session is near impossible with all the distractions of the holidays (mainly sleep). I think i just have to straighten up and realise how quick these months will go, because similarly i won't be happy with a score under 90. If i want it i'll have to get my ass into gear though, because i'm becoming a king of procrastination.
I'm feeling very lucky that i was rank 1 in every subject in unit 3, in an weak-average cohort mind you.
