Submit an Academic Petition or Appeal

Petition Letter: I am a student who expected to graduate in this May with Math general degree.
To challenge myself, I was applied for difficult courses which I do not really need for graduation. However, the things I haven't expected was that these challenging behaviors had brought me a huge pressure recently.
The pressure from the academic and job finding together has given me too strong impact, such that I got strong psychological challenge.
Recently, the pressure I endured caused the mess of my daily life, and I was long-termly under a low mood. I could not balance well both sides of my missions (jobs and academic).
However, these two courses I appeal to drop won't be affected my general degree, and I feel that I might take some pressure out from the academic, so that I could smoothly graduate and focus more on my future job finding.
