we can't pronounce in perfect way like native people because it's a second language for us , but we can pronounce it as much we can by your ways as you said, and hoping to be from ordinary into perfect as a native with practice of course


Sorry , I believe we can
since there are those non native Arabs who could master the language (the Rich language that has a very difficult sound system and letters that aren't in any other language ) and can speak quite the same as real Arabs, We can master English and speak like natives as well
It's a challenge we make by Practicing as you said

and my words is Ethics + School (sometimes in english language Pronounce (C) as (K)
Actually It's all the times that C is pronounced as k except in one condition
When it is followed by these 3 letters
(i(e-y-i

e=center
y= cycle
i=city

so it's S only here and not k
