While reading especially where you were told to try again next time, I was like “they could have possibly told you to switch to another course without chemistry ” but I read to the end and that was what happened.
Once a school had given one admission but failed to meet the requirements, it's a thing they would suggest another course for him or her.
During my NCE in 2012, I wanted to do business administration but I didn't meet the requirements in my Waec but I was given another course and today, I am happy with what I did even though I went for a course similar in my degree.
