You  won't face major problems regarding language at KLE Technological University (KLE Tech) if you are from Rajasthan and don't know the local language (assumed to be Kannada).

KLE Tech offers various undergraduate and postgraduate programs, and English is the primary medium of instruction for most of these programs. This means lectures, course materials, and exams will be conducted in English. KLE Tech attracts students from various parts of India, and English serves as the common language for communication among students and faculty. You'll likely find many students who are not native Kannada speakers.

While English is widely used, you might encounter Kannada in everyday interactions with local shopkeepers, transportation providers, or hostel staff. However, basic English or Hindi (another widely spoken language in India) can often help you navigate these situations.
