regarding the options , i would like to choose option B , due to at home we have time for familiarize with the assigment, we will be more confortable and our mind will be fresh, furthemore would not pressure while we gonna written at class overtinking if the time will be enought or not. On the other hand having more time we can refine the final exam using material by exploring a topic in detail. in mi opinion option A, can not be , because during the academic year we saw a lot information like: dates , events , representatives names ,thats why in my opinion we will need much more time to demostrate our knowledge.
