Learning Suggestion to better understanding on Advanced Microeconometrics (Master Degree Level) I am studying master in Economics and currently taking the compulsory course of Econometrics in which I have problem in understanding the materials. It is a must for me to pass this course in current semester, but I have little confidence to succeed it with my knowledge at this time. The book used in the course is "Econometric Analysis of Cross Section and Panel Data" by Jeffrey Wooldridge.

I don't have the proper basic understanding of first three chapters in the book consisted of The Stochastic Setting and Asymptotic Analysis, Conditional Expectations and Related Concepts in Econometrics, and  Basic Asymptotic Theory. Therefore, it would be tougher to understand the following chapters.

So what is your suggestion for me to figure out this? Perhaps the beginner-friendly books of Statistics or Econometrics? Or other tips and trics?

Maybe some of you have experienced the same situation in the past, then you can share how you figured out and have done with this problem. 

I appreciate for your help. Thanks in advance!
