Section 2 of 3
The graphing pattern is simple to state: type what the question gives you, then read the answer off the graph instead of solving by hand. This section applies it to the question types where it is fastest.
Every chapter has three stages: the lesson video, guided practice inside a live Desmos calculator, and four original, hard SAT-style questions with a timer and a full explanation.
The question types you solve by typing an equation and looking at the picture. These are the fastest points on the test once you recognise the pattern.
The curriculum estimates that this section's question types are 25.24% of SAT Math question types; see how the estimate is calculated.
