Starting in 2016, TJ introduced a problem-solving essay. Every year, this has been primarily math-based on topics ranging from the pythagorean theorem and percent change to midpoint/distance, and triangles. In 2021, they slapped the term "science" on it as well. However, the problem given was still fundamentally math-based. A common question we get from students and parents is how to practice the conceptual material behind this.

Often times, school instruction on the conceptual material needed to succeed is insufficient. Typically, schools emphasize memorization of formulas and numeric answers, instead of **application and word problems. **In order to best prepare, we recommend reviewing the following concepts and word problems:

Math Topics:

Number theory, Set Theory

Fractions, ratios, rates proportions,

**Percentage and Percentage change**Exponents and radical operations

Arithmetic Series and Sequences (e.g. finding the sum)

Geometric sequence (e.g. finding the sum)

Population growth or decline

Simple and compound interest

Direct inverse proportionality

Work Problems

Speed Time Distance

Mixture problems

Permutations and combinations

Probability (coin problems, deck of cards, marbles in bag)

Science Topics:

Experimental Design Diagram and the Scientific Method

Identifying variables, controls

Compare, extend, modify experiments

Reading charts and graphs: histograms, pie charts, scatterplots, etc

Translating data into graphs

Interpolating and Extrapolating

Determining which conclusion is supported by data given

We will be posting good resources and examples for these topics in future blog post. Let us know what you'd like to see next! Email us at __TJPrep@EduAvenues.com__
