I don't know much about the postgraduate entrance examination. The computer of a master engineer should be better than that of a maritime engineer. It has been a long time since it merged with the Institute of Information Technology, and now it has merged back.

From the point of view of computer technology alone, it is better to choose information major or some computer-related majors for navigation. For example, there is a specific name, mainly electronic charts. I forgot, because students majoring in computer science at Haida University usually choose these majors for postgraduate entrance examination, and your scores are not low. I wonder if I can adjust them here. I can only give you one suggestion.

Good luck ~
