The moment he transferred school, he's changing consistently, from being a 'lil smart obedient kid to a worst nightmare to his parents and as a boy. Yes, he is currently experiencing puberty but that doesn't do anything with his studies. The time he met classmates and street friends who became close with him and suddenly influenced him of such normal stuffs in this time; the internet and the game, he just lost focus and deprived himself of learning in school. His growing up routine when he was in elementary until he graduated were all the same. He'll be dropped home from school, change clothes, and then leave home until evening. Or times, he's in front of the monitor, playing computer games. You can easily prove yourself when you observe him and his friends. At school, his friends are BI or plainly BAD INFLUENCE-RS. At home/street, also the same.
