Ammonia stinks like crap.

I failed chemistry. 3/20. I really thought I could pass. I realised that I didn't grasp the concept thus the failling. I hope this late wake up call could get me a pass for CA2 chemistry. Miss Yeo said that we're no longer studying lower-sec science and we could kill the idea of getting a distinction by studying the night before. Wow damn...

Should I clear it or not? Bothering me alot. CA2 this Fri.
