First half of this unit i felt confident with learning the content, after the midway exam thats where it really hit home, the content was hard to learn and took a lot of work. I found other students were struggling through the entire unit and were highly stressed, especially for the final exam. I also found within my class there were a lot of student repeating this unit for their second AND EVEN THIRD time! i believe fail rates are considerably high for this introductory unit which causes a lot of student anxiety early on in semester, but it is possible to pass and even achieve a high score! if i can do it, you can do it! :)
