Is PW (JEE / NEET batch) enough for IAT?

Hi, I want to get into the IISc and I was considering buying the PW Arjuna JEE batch or PW Arjuna NEET batch next year (I am thinking of taking PCMB but I'm not completely sure). Before seniors say nahi ho payega hard hai and all, I'm considering taking PCMB, I'm not very sure about it yet. I wanted to ask you guys whether a PW Online batch is enough for preparation.

Thank you!
