I am writing a argumentative retrospective essay on about my composition and i want to talk about how my writing has improved gradually. below is imy introduction

I have taken a lot of classes in the few years have spent in college. Of all the courses I enrolled for, I have found some enjoyable and some least enjoyable, because all courses cannot be the same. I had different lecturers for all and each courses requires a different type of knowledge, procedures, thought, steps, theory. English 1302 seems to be the most challenging class I ever took because it is an extensive course which made me use my cognitive skills. It emphasis and requires critical thinking, research and documentation techniques, literary and rhetorical analysis and been able to write like a scholar. My writing skills has improved from what it used to be when I first started the class to writing more like a scholar.
