I wuld like 2 suggest U Mr. Ahuja's Book as is comprises of everything. Even Summary format is backet or in box format.
Evan U can go for VG Sir notes, if U want 2 b precise.
Above All, Prefer that book in which u have best comfort level.
Yaar, Don't process much.
One of my frnd had just gone through VG Sir notes only & she scored Highest in DT in May 06.
Its not deal which u r opting, matter wht is the book u refer shud b gone through several times.
Provisions shud b on tips.
All the best.
