My journey to Mastering the Pronunciation of the word/figure three(3)

If you ask my siblings, they will testify to u how they tried so hard to teach me how to read but they were just getting nowhere. I learnt how to read when I was 10 I was in Primary four(4). I have a niece who could read a Bible fluently by the time she was 5 years, not children's Bible but big people's Bible. Back to my siblings, between the age of 6-10 my siblings really tried. I had one problem, cram work. They would show me a word and I would just look at the first letter then just mention any words with those features. For example they would show me a word like cow I would see C and say Cat. When they say no I again say cup. Then they would tell me no, at this point I don't not know what they want from me so I hold my chin and look up trying to think of the word. That usually got a reaction of what u are reading is not up there, look into the book. My siblings were in upper primary and secondary so they felt they could help me with my reading but I made it so difficu...
