Best wishes + Paper Discussion Mains 2023

Had maths optional, got royally fked. Not more than 300 correct. After scaling, not more than 250. Anyone has suggestions for good maths test series?

Paper 1:

  • Found it very lengthy and did many silly mistakes e.g. I got even the p, q limit question wrong. 
  • It seems that either the question was simple and super lengthy or the question involved some trick (unlike recent previous year papers).
  • I left 30 marks in sec A due to paucity of time (e.g. the paraboloid triple integral, the circle ABC and cone). Did everything else correctly in sec A except the extreme point question. Then in sec-B, left 20 marks straightaway in ques 5 due to the laplace and statics question. Further, one part of SHM or vector differentiation might be partially wrong.
  • Overall, there were lesser questions from conventional topics and mandatory questions were harder. Even simple questions had heavy and involved calculations and more chances of screwing up. But given the competition, I can easily see people scoring 180-200 (without scaling). 

Paper-2:

  • Q1 went well - abstract algebra was doable (though didn't consider the `onto` keyword in homomorphism) and couldn't solve the x=1 part in the series convergence.
  • Other questions in sec-A: Did the abstract algebra ones but somehow got even the simplex question wrong (I know I should have practised more). Also left 30 marks due to lack of time.
  • Sec-B - mandatory question was mostly straightforward except the streamlines one was involved and the binary subtraction was tricky. Attempted only one other question in sec-B - the wave eqn one but probably messed up the boolean algebra question (as I didn't have much time left).
  • Overall, barring the focus on abstract algebra, I think this paper was mostly on the expected lines. Again, 180-200 not too hard for veteran folks.

@Davidjones Wave question was pretty standard - initial position and velocity (non-zero) was given. Why do you think it's different? 

@tedmosby I'm having similar thoughts of changing the optional because as of now it has become a huge gamble which can either play out extremely well or fail spectacularly. From this year's paper, it's clear that UPSC has no qualms in lifting trick-based complex questions from random books. So there is a good chance of having a similar or worse paper next year. Which optionals are you considering now?
