Since I was mainly in the lab while in the university, I did not get to know many of the students on campus. There is however events organized by the students which you can check out at the Facebook group "NTU exchange students".
NTU has its own gym and pool facility along with a Sport Club (http://www.ntusportsclub.sg/) with a bunch of sub-clubs ranging from wall climbing, judo, martial arts, floorball, soccer, basketball. This is completely free for the NTU students and a perfect opportunity to meet fellow students, I tried out Judo for the first time which was very fun!
Among the places I really recommend others to go during their stay is firstly Clark Quay which has a lot of nice bars and restaurants were a lot of exchange students hang so it is a perfect place to meet people. Secondly I would recommend the man made beach Sentosa were you can play volleyball and also the national park which is extremely beautiful. Thirdly Also visit the "Marina Bay" with its roof top bar along with the close by "Satay by the bay" which has very nice and cheap barbequed food.
What I definitely recommend you to do during you stay is to take the chance to travel! Singapore is very centrally located i south east asia making it very cheap to travel to Malaysia, Indonesia, Thailand, Philippines and China with the low budget airlines
tiger air and
air asia. A good time to travel is during the days of the chinese new year which is a public holiday. We visited Tioman in malaysia for a weekend scuba diving course in the middle of our stay. This was a bargain costing 3000 SEK with everything included, the trip, the food, the theoretical part everything! And since we performed these theoretical parts in singapore, we could focus on just diving and relaxing while in Tioman. The company we did this at was
Gill Divers and i definitely recomend them, very nice instructors that were really passionate about diving. Since the semesters in singapore start earlier than in Sweden, we ended our projects by the end of april. So we had some time left before our flight back home so we squeezed in a 10 day trip to Bali aswell. But in order to do this, I recommend that you start writing on your report early so that the majority except maybe the discussion is done by the end of your project.
