In your coming examination, you will have 6 examination papers. This week is your 7 days study week.
What is your study efficiency?
Will you pass?(you will pass if efficiency exceed 50%)
Solution:
Assumptions:
for ideal condition:
1. you pay fully attention to your books whole day without any entertainment, talking nonsense or doing anything other than study.
2. sleeping time is 8hours per day
3. eating 3 meals with 1 hour each meal
4. bath 3 times with total of 1 hour
hours of study per day
= 24hours - sleeping time - eating time - bathing time
= 24-8-3-1
= 12 hours
hours of study per week
= 12 x 7
=84hours
however, in actual life, you will not only sleep, eat and bath, you will chat, talking nonsense, blogging(like me now XD), fb-ing, eating snacks, supper time, singing to release stresses and etc.
for me,
fb-ing + eating snacks = 2.5 hours per day
talking(overall) = 2.5 hours per day
singing = 0.5 hours per day
blogging = 0.5 hours per week
therefore, actual study hours
= 84 - 7( 2.5+2.5+0.5) - 0.5
= 45 hours
efficiency of study
= actual / ideal x 100%
=45.5/84 x 100%
=53.57%
because 53.57%>50%, therefore you will pass in the exam. don't you worry^^
Well, i am just boring of studying my thermofluid subject. You know what? I found that engineers like to make assumptions. Almost every subjects i studied is talking about assumptions, after that assumptions, assume in actual life(still making assumptions =.=). We are making assumptions not because we are nooby. It's just because our life is full of unexpected situation. Just like, you are planning your future life, you do not know will you graduate in time and then you just have to assume you can graduated in time. Life is unexpected and full of challenges. So do Engineers!!! In this case, don't think that engineers is not professional enough and Doctors are more professional. Is my assumption correct? huh? Yea?
haha..ok..that's all for today. If i am not going off now, then my efficiency will drop and drop and drop~
Gd luck everyone! For your final!!! aza aza fighting!!
