Guidance needed for Mathematics Optional

noob_19

I'm new to this forum..n someone told me that guys here are very helful..so thought of putting my queries to you guys..
first of all i want to ask about the booklist for covering the entire mathematics optional..i have been through prakash rajpurohit sirs' blog for the booklist but still wanted to confirm if it's the same in the present scenario or not..those who hav attempted in past one or two years can give a better picture..
secondly since am new to UPSC can you guys suggest from where i can purchase these books specifically because i checked prices of certain books online and its really high..so if i can get a photocopy or some other cheap alternative of those or any pdf material...
and finally if you can share your valuable strategy for the same ?
