No. Dont go for Dinesh Madan, its language seems easy but its not module type language and wont fetch marks, Manish Valecha has very small font and too much coloured book, at the time of revision we cant cover it fast.
I would like to suggest you something else. Try it.
1) buy ISCA Re-Engineared written by Bhinang Tejani (Suchita Publication Book ) Rs. 480/- Complete coverage of module in a very understandable manner.. Read it 2 times
+ you can cover fast by Vishal Sarogi's book also. ISCA Simplified. Both books are good.
then read
2) G Sekar's "ISCA Question bank" Rs. 350/- (Padhuka Prakashan)
You need to read and memorise ISCA atleast 4 to 5 times otherwise its not going to be recalled in exam.
i bought these books from MakeMyDelivery . com
all the best
