Best reference book for CA Final G-2

Hi

I am preparing for Nov -19 and I am left with group 2 of Final .
Can anyone please suggest me additional study materials which is good for getting an understanding on practical questions of DT and IDT, though ICAI text is good but still not like what we had earlier practice manuals.

I felt ICAI text is not enough as solving RTP and MCQ of institute was quite a challenge.

Also please suggest good authors for MCQ books.

It would be great if some one just gives a guidance on how to go about preparing group 2 .
