A few questions to students

Many teachers often say that, when students get good marks they claim to be because of their own effort and when they fail or get very less marks, they blame it own the teachers.

I want to ask this questions to students in open. Any student can join the discussion. Whatever you post, let it be your own genuine answer.

Here are the question for students.

If you get good marks in Physics, is it because of your teacher or because of your own effort?

If you don’t  get good marks in Physics, is it because of your teacher or because of your own lack of practice?

Teachers are also welcomed to post their response.
