On the other hand, Business decreased at the end of the period, while Medicine was always the lowest subject during the whole time. In 2015, Business was the most popular choice for international students, with about 500 students. This number went up to 600 in 2019, but then it dropped to 450 in 2023. However, Engineering showed a different trend. It started at 300 students in 2015, which was lower than Business. It grew steadily every year. By 2023, it reached 650 students and became the highest number in the chart. For the Medicine subject, it had the lowest number of international students between 2015 and 2023. In 2015, there were only 100 students studying Medicine. It went up a little bit to around 150 students in 2023. The number did not change very much compared to the other two subjects.
