One of the leading private universities in Thailand. Located in Bangkok, but very far away from downtown (not far from the airport), in an area called Muang Ake.
Rangsit offers courses in engineering, IT, medicine, architecture, design, humanities and social sciences.
Most buildings in Rangsit have air conditioning; if you go there, you will understand how important this is. Rangsit is also home to a large amount of very peaceful stray dogs. There are free Internet-connected PCs scattered around the campus.
