I had refered 100% khalid & Rasmussen & a @ 70 % of Jawarosky
I didnt even touched the RH although many my friends told its good book.
But for concepts part I will strongly reccomend Khalid.
I have read almost each word in khalid book.
I solved @ 12 good (markus green, mindQ,sun guogiao) mock exams which developed the 'way of thinking'.
Hope this input will help you. Any further queries please feel free to ask.
I wish you Best of luck for exam.
