Tackling the Wonderful SAT TEST

SAT is literally in 3 days! That is scary but excited at the same time. In Math essential, 95% of the class time is strongly devoted to SAT math section preparation and I been doing that for over 4 weeks now.

Most of the time, we worked on filling the individual math content, such as the system of equation, right triangle, circle theorem, and remainder theorem. I pretty confident with the materials, but my two biggest flaws are the limited time and strategy that I approach the questions.  

Jeff Boucher, our math facilitator, had guided me through the differences approach to solving a problem. Those approaches include the plugin, read the desire findings, and work back from the answer choices.

As I spend some time working on different types of problems, I started to see some patterns and methods that work for me.

The only way to beat the time constraint and the test is to practice. So, I hope everything going to turn out well.

See you SAT!!

AP Statistic

We has jump another big step in Math. This year in Math essential, I’m taking a college course, AP Statistic, which is a very challenging and involve a very high critical thinking skill. Not like other math we are doing, AP stat is quite fun, it is more to thinking about all world data rather than calculating the math like algebra. Moreover, I personally think that AP stat course will be more applicable to me in everyday life and in my further work. AP Stat is a lot of looking a bunch of data from whatever you want to investigate and analyse the association of those data. For example, I can collect data of people from various level of education and their income, then I can uses these data to analyse the correlation and the association between these two variables. The two main textbooks that we used to learn the materials are The Practice of Statistics and the Barron AP statistic test book. However, as we learning the concept, we realize that it is not enough, therefore, we uses many more online resource such as Khan academy, Edx course video and many others worksheet out there. So far, we finished four chapter:

  1. Chapter 1: Exploring Data
  2. Chapter 2: The normal Distribution
  3. Chapter 3: Examining Relationship
  4. Chapter 4: More on Two-Variable Data

Out of all these four chapter, my most favorite is the examining relationship between the explanatory variable (independent variable) and the response variable (dependent variable) to determine the correlation, form, strength, and the observation association. But the most exciting part of that chapter is finding the least square regression line, which is the line that predicted a response variable at a given response variable. This course will be one of the course that I will put a lot of effort in order to succeed in the AP test, but especially understand the idea behind those data.
