Hahaha😅 are we living the same life because this is honestly me, studying the same subjects and all.i get like this so often to the point were i tanked my history coursework, got a chance to redo it and i think i tanked again because i used other peoples work as a refrence which may probally jave come off as plagarism. Tbh the best one can do is to get someone who lives with you (mum, sis,bro by any chance) to continously check on you and force you to do the work. Like force them to demand the work that you'd say you'd do from you. Because honestly even though it will feel annoying at times and toy still might fell nauseous. When you get into exam rooms you will know more thatn you thought. Good luck though 🙏
