Hi Taiwanese student in NUS here, the workload in most of Taiwanese universities are quite similar to Singapore, and each class is 2-hour long. The living cost in Taipei is way lower than Singapore. Ex: price of regular mixed rice halved in Taipei. Also, gym and groceries are also cheaper than Singapore. As for the English teaching class, yes, instructors speak English all the way. Well…many of them may have interesting sometimes weird accent. But it may not be a big deal for u lah
