hi,
I too prepared for 1.4 using K & B.
Yesteday after i read your post i explored Khalid Mughal Exam, and i was shocked, and again it was till today just one hour before, i just completed with 54% only. Its my Luck, just pass.
I did see a lot of questions in the style of Khalid Mughal Exams. i am not telling K & B is not good, but should practice other mocks too.
Unfortunately i did not have enough time after reading your post last night, so i could not get trained with Khalid Mughal Exams.
Good Luck.
