Group 2 final books

i am appearing for CA Final exam group under new scheme. I want to clear the exam in May 2022. It is not possible to prepare Institute study material since there is no much time. It is requested to suggest any best study material for Group II subjects viz., Direct Taxes, Indirect Taxes, Strategic Cost Management. I may be wrong in not choosing institute materials. However, keeping in view of the time available I want to have readymade material. Please help me in suggesting the good study materials for the above subjects.
