Is it over for me

I'm a student of stream 2. As you can see below my study centre gave me very less marks in my practicals even though I was the only one who even made those practical files.They even aksed bribe for practicals(I didn't wanted to get failed in it so I gave them)

I only got 54% in total isn't there any way to improve my practicals marks I just want 60% anyhow. Does I have to reappear for both theroy and practicals?

[Ignore my physics practical marks it was TOC]
