Never and cologne is disgusting . The douches took over for years , I admit that . I ' m usually wearing a lab coat or a Gi . <| sep |> Not the exact situation , but I ' m from Canada and has a good discussion with some friends from Norway about this , it ' s a similar deal . Thing is , with us , these assignmentslabs , etc . are mandatory , but they also contribute to our total course mark , making our final exam worth less . For example , in my current circuits course , labs are 20 %, assignments are 10 %, the midterm is 20 %, and the final is 50 %, all summing to our total course mark . I remember being very surprised when my friends mentioned all of their assignments and such were optional , but the finals were worth 100 % of the course mark . For us , there ' s no rewrite options or anything on our finals , so even the thought of a 100 % final is very stressful . It ' s very rare over here , but it does happen on occasion . Of course , it ' s a doubleedged sword , because while we do have less stress for our finals , we often stress during the year about getting our assignmentslabs done on time , since we often have a lot . Many of my friends feel finals are the least stressful time of year because we don ' t have to worry about assignments or labs , we only have to study .
