Blitz Series (Maths)

Are blitz series maths mocks by parmar unnecessarily hard, 1-2 can understand but literally every mock is getting tougher only, even mains paper also not this tough and time taking. I know it's better to be ready for that one day where your shift paper may be hard, but with sectional timing introduction I don't think Maths paper is going to be on tougher side now as sectional timing is itself a challenge
