I can understand you must be really under a lot of pressure.
I know that it’s not your fault and it doesn’t mean that you will not succeed this time.
Let’s not focus on what has already happened, let’s focus on what can be changed.
You should plan out your study in a way that you secure good marks.
Refer to notes, past year question papers and youtube for your doubts and concepts.
Don’t feel upset if people compare you to others and your marks don’t define your success. So relax and move forward in life and continue working hard. Don’t give up
