In US PhD system, the newly admitted PhD students spend the first complete year doing different lab rotations so that they get acquainted with the different lab cultures, lab groups, their potential supervisors, etc and chose their lab by the end of year and so they get to make a more informed decision on choosing the supervisor and lab after careful analysis and exposure thereby making better matches between PhD students and supervisors and lab but in UK PhD system we need to chose the supervisor and the lab prior to admission and thereby increased mismatch takes place. Do people over here think that we should also have the US system so that we also get ti make more informed decisions??????????
