In Kazakhstan, design programs admit students through creative exams such as drawing, composition or painting, while on the UNT you take only the compulsory subjects. A bachelor's degree takes 4 years. Design is taught, for example, at the Zhurgenov Kazakh National Academy of Arts and the Kazakh Leading Academy of Architecture and Civil Engineering.
You can also start at a college after grade 9 or 11, studying graphic, fashion or interior design, usually for 2 to 4 years. Many designers also take online courses. Employers often care more about your portfolio than your diploma, so start saving your best work now, even school projects and personal experiments.
