thats will only improve ur grammar and spelling, its not going to help u to speak english well
the only way to speak well is through conversation
u can write a really good english essay but u might not able to express/present by speaking
dont be shy to talk in english
good luck
that's my problem now. that why i have created this post and wish to improve my weaknesses. i have the motive but don't know how to start and implement it. anyway, thanks for your guidance.
