Are newer facilities necessarily better than older but well-used ones?

Not necessarily. Newer facilities may offer advantages such as newer functions or safety features, but older facilities can still be useful when they are properly maintained and support the learning objectives of the classes. What matters is not age alone, but also performance, ease of use, available access time, and support arrangements. Because facility conditions and access vary by university, faculty, and academic year, check the official information for the program you are considering.
