"alphabets,phonetic alphabets,days name,months name,spellings,pronunciation"and so on.
after they both were satisfied that the son has learnt the basics of english, the father thought to take his dictation.
programmer father : "son,are you ready to give your first dictation?"
son : "yeah dad, i am pretty much ready for the test and feeling over-joyed too."
