I have 43 percentage in plus two can I go into mechanical engineering in a good collage

Hello aspirant!
Well the answer as no for most of the top universities and colleges ,as most of the Institutes have their own eligibility criteria for btech  as you have got 43% in your 12 the class then you cannot even think about NITs IITs ,IIITs as jee mains eligibility criteria is to have min 75%

It depends from which university or college you want to pursue you mechanical engineering as most of the universities require at least 70 % in class 12th with relevant subjects so you can not expect your admission in them .

There are many universities like aktu ,du ,shiv nadar university,thapar university all of them have their own eligibility criteria like  aktu require 45% marks atleast in class 12 th similarly shiv Nadar university require pcm %>=80%

As your 12 the percentage is very low so you can not expect your admission in most of the good colleges

Hope I have resolved your query in case of any other doubt you can get back to us
