Want to start preparation for AIAPGET

I just got done with 1st year university exams so was thinking about preparing for AIAPGET from 2nd year as I'm from private college and I really want to make to a good govt college.I was thinking of joining Ajit Patil sir's classes but I'm highly confused should I join from 2nd year itself as I'm not sure would I be able to balance it with regular college but If it's a wise decision to start from 2nd year I'll manage it anyhow;If not then plz guide how should I start preparing my 2nd year so that it will be also helpful from AIAPGET's pov and also plz tell me any free resources from which I can start preparing and also plz share the list of books for AIAPGET. Plz seniors throw some light!!! Thanks in advance:-)
