tomodachi, relax. While CSE does have a lot of antisocial basement-dwellers and is very gender imbalanced, there is an extremely large social circle (with a ratio of girls that is significantly higher). Of course, the literal basement that is the student lounge in K17 doesn't help with the image, but what most non-CSE people don't know is that there is a large and open student-only office available in the basement which is filled with students (both CSE and not) every day of the week.
Our constituent society is considered one of the most active in the uni and runs free barbecues every single week, as well as at least one free event every week. They also offer a (highly succesful) camp for first year students enrolled in a CSE course (this includes engineering students taking COMP1911/COMP1917) - last year there were close to 100 attendees!
Meanwhile, the School of Computer Science runs the somewhat lame-sounding "Student Network" - I assure you it is by far the easiest way to quickly make a ton of friends in CSE (the next easiest way being the student-run First Year Camp, but that only happens around Week 3/4).
Finally, there's CSE Revue, which is an annual comedy sketch show produced entirely by students. This isn't some small little thing either, it's a big-budget (costing $50,000 to put on), ~300-person undertaking, each and every year. The best thing about getting involved in Revue is that it's open to anyone, so you meet a ton of non-CSE students as well. Revue also forms a tight-knit group with the other two major Revues (mostly with Med Revue but also with Law Revue). As a result of this, you get to be social regularly with students from all over the uni.
Basically, if you're really worried about making friends, just do the following:
1. Join the Student Network - I guarantee it's worth it
2. Go to the First Year Camp - especially great if you're part of the Student Network since you'll have already met a ton of people going
3. Go to CSESoc events and BBQs
4. Take part in the Revues
