Impact of PhD cgpa in academia and industry I'm a Physics PhD student in a US university who qualified for the PhD level and waiting for the comprehensive  test. 

In the first year of my PhD, I wasn't able to cope up with the pressure and  that caused bad grades. The result from first and second semester is below: 

A, B, B ;  A, B+, B+. 

In the second year,  I eventually  understood  the pressure and was able to cope up the  coursework pressure along with the  research pressure. And, eventually I did well  in the second year. My result is: 

A, A, A  ; A+, A+, A 

My question is how bad influence will my overall score appear to the academia and industry? 

NOTE: My supervisor is pretty happy with my research work.
Academia and industry largely do not care about your grades as a graduate student. The only exceptions are certain large corporations that have cutoffs for the GPA for graduate as well as undergraduate studies. [I have worked for such a corporation, so this is not idle speculation.] Even then, such cutoffs are not absolute—if a hiring manager wants you badly enough, they can petition for the requirements to be waived.

Academia does not care about your grades: your promise as a successful researcher and colleague is the primary consideration in getting hired as a postdoc.
