To study mechanical engineering or industrial machinery at university, you usually take maths and physics as your UNT profile subjects. A bachelor's degree takes four years. Universities that train these specialists include Satbayev University in Almaty, L.N. Gumilyov Eurasian National University in Astana and Abylkas Saginov Karaganda Technical University.
There is also a college route: after grade 9 or 11 you can enter a technical programme, qualify as a technician and later continue at university on a shortened programme. This path gives you lots of practice. While still at school, physics olympiads, robotics clubs and engineering projects are a great way to test your interest.
