I got 72% in Diploma in mechanical branch. Which field is good for engineering?Marine aeronot or mech

mechanical is good because after finishing engineering study one year course of marine and aeronotical you get 2 degree and diploma then you are the most valuable one in the job field..

Well all these streams are good but if you have interest in physics and aerodynamics then go for aeronautical. If you are interested in fluid technology and machinery parts then choose mechanical or else marine.

Mechanical because you have the knowledge of this course and you have good percentage in you Diploma.
