7. hello sir, ur videos r very helpful.. this whole site is..
sir, d calculator u r using, is it allowed in mains xam..??
if not this, can u plz suggest some model which is allowed..
thank u so much sir..

1. According to UPSC rules (given in official notification),
Non-programmable Scientific calculators are allowed in the mains examination. (e.g. The one I used in that video.)
If you’re living in a big city, I suggest you make trip to the biggest stationary shop, and manually check the features of various models. Ideal model should have easy Statistics mode.

Otherwise, There are many models available in flipkart, if you want to buy it online.
