I will be having my final year study in mechanical engineering. Now, I am considering what to do... I believe that both my characters and ability are not quite suitable to work outside as an engineer. I think I am a somewhat theoretically inclined person, so I have identified pursuing an academic career as my aspiration before. What I would like to do is more like applied mathematics... But I will say my university education does not provide me with a solid background in mathematics. And I am definitely not those clever math genuis that have special insights into math... So, I am wondering what I shall do... I will say I have a rather weak math background now... I am therefore conidering whether to do a second degree in math or phy...but that means I am going to spend 3 more years as an undergraduate student and a large sum of money... I am also considering to do a master of science in applied mathematic in my country. But provided my weak mathematics background, I am not sure if it is a good idea to do so... I am quite confused and hope to listen to others' words.
