Other state students might face some major issues at Anna University. Some of them are:
Language Barrier: Almost everyone in Tamil Nadu converse in their mother tongue. So students from other states might face language issues outside the campus.
Climate: Chennai experiences a hot and humid climate throughout the year. The unbearable heat might be a serious issue for someone from a cooler state.
Food: Although Chennai offers both veg and non-vegetarian, if you are a true North Indian you will definitely miss North Indian food here.
Metropolitan: Life in Chennai is very fast-paced and can seem overwhelming for anyone. Also the pollution levels are high.
Whether Anna University is good for other state students actually depends on their capability to endure the above factors.
