How my preperation goes?

No joke. Those are the materials i flip through each time when chem assestments come. This time, things seemed never end. There are just too many things to cover. Anyone lend me a hand please!!!

Meanwhile, i am still wondering of her sudden hostile towards me... Why? Right, that's outa my topic. I'm pulling out of the excursion. Yes i'm! Rather spend more time with my family... Obnoxious community! Indifferent attitude!!
