*CHEMISTRY* Chapter 1 :
Do all the definitons, on a paper make a chart and with arrows mark trends. Make a table which tells the factors, Highest , lowest. Write keypoints of give reason answers eg  : Chlorine has more EA than Fluorine : F - small size - electro repulsion 

Chapter 2 :
Do the definitons. Structure of all electrovalent and Covalent are similar, go through them once if you are confused, DON'T forget to write the electrovalency, do the lone pair effect and NH4+ and H3O+ coordinate bonds. Make a two column table and write the difference in properties of electrovalent and covalent compounds in KEYWORDS ( I am emphasising because long answers are boring to read , takes time but keywords can instantly make you remember the crux of the matter).

Chapter 3 :
Do all definitions . Make a table and write the general formulae of preparation of acids and base : such as H2 + halogen = acid; Metal + O2 = Base ;(there are more)
Go through the uses and the pH paper page. Learn the change in colours of indicators and the difference between them. Learn the SI Unit of pH and pH = -log H+
For salts learn solublity , just the general formula of all salt preparation ( w/ insoluble and soluble / dilute and conc and temp written) . With this you can make your own equations. Go through the examples once. Go through the preparation of specific salts with emphasis on FeCl3. Learn the properties, WOC , deliquiscence, efflorescence , Hygroscopy and Hydrolysis - learn the pH of solutions.

For Stoichometry - Learn the 2 laws , go through examples and understand what it means : Gay Lussac's is only for volume , Avogadro's can be of moles / mass / volume
Then solve last 10 years and behind book questions.
