Hi Khaled
I agree with Dr Maha that you have to read and try to study your 3rd year lectures first before we go through any revisions because it will be useless without your active participation..It is my pleasure to share with Dr Maha in the revision on the date you all agree on..Regarding the 2nd problem solving, please set a date which suits everybody before or after the revision and tell me about it so we can do it together...Best of luck to you all !!!!!!!!!
