If you see care fully, you will find there is everywhere chemistry in life. Don't learn the chemistry as one of bookish subject. 

• Just go through the various concepts of chemistry. 
• Write everything on the paper. 
• Practice daily
• Think about the material all the time.
• Learn the material in small concepts, with figure and diagram.
• Concentrate on your work and live active
• Re-read the material.
• Write out everything you know.
• Work the problems without looking back at the chapter.
• Attack on study rather than defensive.
• Check your answers.
• Relax on the test.
• Learn from your mistakes.
• Get help when you need it.
• Feel the confidense.

Final words

Make concept map of each chapter and revise it every time.

Devide the chapter into

• Derivation based
• Numerical based
• Conceptual based

Good Luck
