Hello,

Some of the most important topics of stats to crack bhu msc statistics entrance exam are-

1)Probability and its subtopics(Conditional Probability,Unconditional Probability,Bayes theorem)

2)Distributions(Uniform Distribution,Binomial Distribution,Poisson distribution,Geometric Distribution,Hyper-geometric Distribution, Continuous univariate distributions,Normal Distribution,Exponential Distribution,Gamma and Beta Distribution)

These are some important topics but I recommend you to try covering as much syllabus as possible as there is almost even distribution of questions from each unit.

All the best!
