Hi All, I am preparing for IZO 047, IZO 042, IZO 043 certifications. I have Oracle University Study Material which i got from NIIT but i am finding it inadequate for IZO 042 exam. Can you please suggest a good book or books for the above certification and also where i can get it from. I would also like to tell you that i have checked Flipkart.com (in India) and Amazon.com but am not sure which book to purchase. Kindly advise. Thanking you all. Regards. Sameer.
