frustrated

If I had to rate them 0 I would in a flash, I was a student there last year studying towards my BTech and I was left with tht module and I "failed " by 2 points but when I wanted to remark my paper because I know how I wrote and they refused to have me there and when my paper came back they never even showed me my moderated paper so that I can be at ease that Yhaaa it is what it is ...do u know how expensive it is to study
