Are You Smarter Than a High School Freshman?

Ninth grade is often the year math starts feeling genuinely abstract, biology gets its first real dose of cell structures and genetics, and geography zooms out from the home country to the rest of the planet. This quiz pulls from all three.

Algebra I, Step by Step

Freshman algebra leans heavily on solving for an unknown and factoring expressions back down to their simplest pieces. Take 3x - 7 = 20: add 7 to both sides to get 3x = 27, then divide by 3 to land on x = 9. Factoring works in reverse, turning something like x squared minus 9 into (x - 3)(x + 3), since those two binomials multiply back out to the original expression.

• A linear equation in slope-intercept form is written y = mx + b.
• 2(x - 3) = 10 expands to 2x - 6 = 10, giving x = 8.
• Checking your answer by plugging it back in catches most careless mistakes.

Cells, Genes, and the Shape of the World

Freshman biology usually introduces cell structures like the mitochondria and the basics of how genes control inherited traits, while world geography courses map out major landmarks like the Nile, the Sahara, and the mountain range that splits the Eurasian continent in two.
