Thanks for the words of encouragement. I want to be a pharmaceutical scientist and that's why I am studying hard for chemistry, which is very mathematical and I did not study maths after high school, so integration/derivation and fancy terms like differentiation calculus are very hard for me to ponder through. But the good news is my college professors are ready to help me. They tell me it's not my fault I forget everything, it's that the subject is volatile. I just hope it's the truth.
