Hey,
I am a new PhD scholar, joined in March only. I did my M.tech in Biochemical Engineering and was looking for PhD. However, I was not sure about my research area. I grabbed the very first opportunity I got for PhD which was in Chemical Engineering. But now I am feeling totally exhausted because the coursework requires me to study engineering maths (I am from a biology background) and computational fluid dynamics as well as coding in MATLAB. I am unable to understand any of it as I have no basics about the same. What should I do? Should I quit and look for PhD somewhere else?
