Don't worry, the chemical engineers I used to work with had plenty of time for drinking and debauchery during their degrees.
The people who say they had no time to do any socialising during their degrees were either not that bright, doing it wrong e.g. memorising every single formula that has ever been used when, unless they are empirical or experimentally based, can be derived from first principles, or are trying to overcompensate for poor social skills. The later group will probably find themselves unemployed, too, given that social skills are just as important - in fact probably more so, overall - than technical skills when it comes to jobs time, as confirmed by anyone who's been to an assessment centre.
