my self (myself) don't put space between them coz they r considered one word

i'm serkay and (, )when you are listing more than 2 items dont use and and and .. just put it before the last thing u r listing i am 183cm and student ( it would be better if you said i'm serkay , 183 cm and i'm a student ).i am learning English, cuz i didn't pass exam and i have to pass exam (it would be better if you replaced it with it .. repeating the same word not a good thing at any language soo it would be good if you said i have to pass it ... yours isnt worng but not perfect ) in September so i am learning English ( i don't know why you repeated it again .. you have already said it before )

good job keep it up

good luck
