I was able to do what I needed but I am not sure about future applications. Also, I thought I received a 70% Discount for signing up annually but I did not receive this.

Good Product I need a pdf editor and I use this product because it is a cheaper alternative I like and need a product that allows me to edit and mark a pdf file. The Editing feature on this product was hard for me to master

I’m new to using any type of online… I’m new to using any type of online filler, and the support I got from pdffiller was beyond my expectations, I highly recommend.

Easy to Use It's been fantastic to use to add whole sections into a document without having to re-do everything. We haven't required something like this often, so I love that I can access this software for free, on an as-needed basis. Haven't needed to use the software enough to have any issues arise that I couldn't troubleshoot on my own.

Statistical core concept. Descriptive statistics, distribution, hypothesis testing and regression. Bayesian probability theory. Introducing statistics in machine learning.
Use distributive practice rather than massed practice. Study in triads or quads of students at least once every week. Don't try to memorize formulas (A good instructor will never ask you to do this). Work as many and varied problems and exercises as you possibly can. Look for reoccurring themes in statistics.

Yes, the knowledge is necessary, but it is not sufficient. Statistics doesn't make sense to students because it is taught out of context. Most people don't really learn statistics until they start analyzing data in their own research. You need to acquire the knowledge before you can truly understand it.

Statistics is only hard if you haven't memorized the formulas. But, with the programmable calculator, you don't need to memorize. So no, learning statistics is not difficult.
I like calculus better than statistics, but when it came down to it, for me at least, statistics was the easier course. I can see why someone would feel that statistics is harder, however. Statistics requires good reading comprehension, as the word problems are generally less straightforward than that of calculus.
AP Statistics is considered to be slightly easier by most people's standards, but it's still an AP class. If you're not majoring in a STEM field or applying to the most competitive colleges in the country, you won't be faulted for taking AP Statistics instead of AP Calculus.
