Hey, 

Chemistry is classified as organic chemistry, inorganic chemistry, physical chemistry. Be aware at which part you are good at. Check out the weightages of the chapters. Brush up on the chapters you are good at and do not( I said do not) study any new chapters right before the exam. According to me, inorganic chemistry and physical chemistry are pretty easy. Inorganic chemistry might have a lot to study and remember. If you are good at remembering stuff, I'd suggest you concentrate on inorganic. As physical chemistry has formulae, practicing it would make things easy for you.  Organic chemistry is entirely dependent on the basics and IUPAC names. Be sure to keep an eye on the weightage about which holds the most. For inorganic chemistry, the more you revise, the more you attain perfection. 

Hope you do well. 

Thank you
