My K2 boy have problem in recognizing words. what should I do ?

i send my boy to DAS for 2 terms. he didnt pick up anything there. he cant read, he cant spell, wordingss are mostly mirror imaged. i send him for phonics class at icanread, edufarm also no use. in the end i engage a private tutor for him. he start to read only mid of k2. he is in p1 now. he scores band 1 for english n math . band 3 for chinese. lol . the results are good enough for me . u have to understand y is your boy not able to read. is the lesson boring ? attention span ? i realisse he need 1-1 . even in a small class, his mind drift off. Find out the problem before sending your lo to various class. i spent more than 2K then i realise the problem !!!!
