Urgent Pl Executive Programme and Professional Programme Books

Institute study material is enough for study.You can take suggested answer of the institute for past year papers.

For 10 year solved paper you can by reliance solved scanner.

But in my opinion institue study material and suggested answer is enough to cover the full syallabus.So you should prefer it.
