Feeling confused about case studies is completely normal, especially when you have been staring at them all night without a break. Your friends might seem confident, but chances are they are just as lost as you are and are simply better at hiding it. One thing that helps is stepping away for a bit to clear your head, then coming back and writing down the core problem each case is trying to solve in your own words. It also helps to look at the questions your professor asks about the case, because those usually point you toward what really matters. If you are ever planning travel to Turkey, check the Turkey Visa Policy page since some nationalities can enter without a visa while others need to apply online first. Take a short walk, grab some coffee, and try explaining the case out loud to yourself or a friend.
Tegul Saulė Lietuvos tamsumus prašalina!
