You mean the Institute of Materials Research? First of all, if you are admitted, the score will be different. The academic master's degree is 370 this year, and the engineering master's degree is 360, which is material engineering. There are also differences in future course selection, but the differences are very small. It's hard to say when you are employed, because the country didn't graduate a master's degree in engineering until 2009. Of course, in theory, it must be an academic master.

The chemistry department of the Faculty of Science also has these two majors. Generally speaking, people will apply for academic majors when they apply. If the score is not enough or the retest result is not satisfactory, transfer to a professional master's degree. Personally, I don't think there is much difference.
