Do you waste your time by using your phone even in a bus or anywhere, its not a good thing if you are doing A /L. what I suppose you to do is download "Adobe PDF" to your phone, then go to http://nie.lk/pages/syllabus.asp (For Sri Lankans other country Students download it from there Country website) and download teachers guides books to your phone. Just think if your in a bus people will think your reading sms but dont care whatever they tell. Recall your theories according to teachers guide book. Its easy because there have some examples also. Special For A/L Chemistry.
