@ All : Been very busy all these days with my business, so couldn't thank you promptly. Thanks a lot guys. Hope I can be of better help to you.
@ Raghav: It would be great for you to go with vaitheeswaran as that is more than sufficient for theory. Practical problems alone go with a book which has a lot of those. If bangar has got sums then go with bangar for sums. All theory, please go with vaitheeswaran only.
Yes for both DT and IDT case laws are very important
All the best
