The chemistry story

I was mightily struggling with chemistry. Then one evening I decided that I have had enough of that. I went through the chemistry book stopping in every significant place which was not clear to me. My grades became manageable and from then on when facing difficult parts I knew that I can not skip them altogether, but rather I need to gain at least a vague understanding of them in order to stay in the business of chemistry. It is nice when all you need is in a single book.
