BS or bust - TESU BS in Data Science and Analytics

[monroe18]

many courses from statistics.com are really easy

I've done
Introduction to Python for Analytics
R Programming - Introduction 1
R Programming - Introduction 2
R Programming - Intermediate
SQL - Introduction to Database Queries

the sql and python course are just too simple

both of the R intro courses were simple, and kind of fun and interesting
the R intermediate course was ridiculously difficult
I did not know enough statistics when I took that course
there was no statistics review or R review -- they just assumed you knew the basic/intro stuff  
I passed with a very good grade, but had to spend many nights searching youtube and google trying to figure out the math for a particular statistical concept  

I tried the R advanced -- had to quit the 2nd week -- had no idea what they were talking about

This is great information, thank you! Did you have any experience with R or Python prior to taking these?
