ASAP please, Good evening

Good evening ..

I'm a graduate student in king Abdulaziz University and I'd like to do a paper on ( English pronunciation problems facing Saudi intermediate students in the letters *P* and *B* )

First, I'd like to have your opinion on this topic.
Second, I would like to know if there are any helpful information you would kindly provide me with.

Thanks

[You are a Saudi, whose native language is Arabic, and who has learnt English. You are better placed to deal with this than most people in this forum.

What problems do they have?
