Hi Girl !!
First of all I would like to say that I was not good in physics until 2015 when I improved myself a lot…. but the major problem which I faced was lack of practice and obviously not focusing on the concept of problems.
My Teacher Dr Arindam Sarkar (MBBS, RG KAR Medical College) who taught us physics had once told me : ‘ Ek Acha Student kabhi calculative sums pehle nhi karega chahe wo Formula based hi kyun na ho, humesha theroteical aur conceptual sums karega kyunki usmein calculation nhi hai”
I followed this and had I not done Two silly calculation mistakes my score would have been Increased from 112 to 122 and I would have got a rank within 6500.
So My First Suggestion is analyse urself and see why you got so less in physics either in test series or routine tests or previous NEET only.
