I started with psychology...Now the problem is that the books my brother bought for me were of intermediate (Shehr bano and Mah Nazir).Initially I didn't know that shehr bano also wrote the BA books (we botha re layman when it comes to CSS)...Now the thing is I am done with 4 chapters and I have written all over the books so now they cannot be returned...I was hoping if I can study from these books and clear my concepts and and can get fieldman book for helppp..is it ok
