So our group got this shitty topic about Fluid Buoyancy and Bernoulli’s Principle. The last resort I could think of, as a leader, was to adopt someone outside our group to help us. I JUST CAN’T SIMPLY UNDERSTAND THAT WHATEVER TOPIC OUR TEACHER GAVE US.
P.S. I just realized how hard it is to be in a group that not even a single person knows the subject well.
