Hey guys, dont know if this is the right place to ask, but here i go.
I am doing A2 Edexcel maths right now, and I was wondering how much of S1 (statistic 1) I need to know to get good marks in S2 (+90%).
I have always struggle with statistics, it was just lack of interest, no revision, crappy teacher, and no foundation for stats. I mean i still dont fully understand how histogram works (i dont know what goes on the y axis and how to find width or something)
Anyway what i want is an A grade, so i want to do well in S2. I didnt know much about S1, but last minute revision and doing a lot of past paper helped me to get a borderline C.
Now i am doing S2 (have an exam in 2 months) and there is a lot of words they used which i dont understand. Variance, distribution, probability density function, cumulative probability density function,etc. Now I personally find S2 easier than S1, mainly because it seems like the entire S2 modules is based on 1 area, and for practice test, i can revise the modules and know how to answer the questions, but i dont understand the topic fully, and with this much revision, i am kinda overwhelmed and dont know where to start.
So I am asking u guys, where to start looking for S1. How much of S1 is in S2, and what chapters i need to focus on.
