To become a marketer you can take a 4-year bachelor's degree in Marketing (group B047 Marketing and Advertising). The UNT profile pair is maths and geography. Marketing is taught, for example, at Narxoz University, Kazakh-British Technical University, Almaty Management University and Al-Farabi Kazakh National University. Some universities also run separate digital marketing programmes.
Students learn consumer behaviour, market research, advertising, branding and digital tools. You can try it at school: run the social media page of a school club, help a local business with its ads or start a small project and count how many people it attracted. Examples like these are useful for your portfolio later.
