first thing is ur requriment. if u want to go for solving of numericals in physical chemistry then p.bahudar is best.
30 years iit papers will give u an idea abt how different type of questions are asked at iit level. eventhought u solve last 30 years but pattern keeps on changing and none of the questions get repeated at iit so it just for practice after u have completed ur coures.
