Lol, i only studied the globalisation topic the night before, which was from way back last year and never got a chance to study the other 3 topics. Study plan was really really bad and untimed but i think i did alright in my eco exam (CSSA). Thankfully things seemed to stick in my head from class and i felt the exam was wing'able.
Just take a short break if you need to after a decent block of study. Helps keep your mind focussed, if you have other exams after eco that are close together then maybe its not a good idea to stay up really late as you'll burn out for those exams too.
Good luck!!!
