ACT preparation should be section-based. The current core test includes English, Mathematics, and Reading. Science is optional in the current format, and Writing is a separate optional essay. That matters because your practice plan should match the sections you actually need.
Start with timing and accuracy by section. English rewards grammar, punctuation, sentence structure, and rhetorical choices. Math requires fast recognition of algebra, functions, geometry, statistics, and modeling. Reading needs passage strategy and evidence-based answers.
How to study ACT
Use the ACT sections page first. Then run the ACT Practice Test in section blocks instead of treating every mistake the same. For score interpretation, continue to ACT scoring. Before a timed run, read ACT format and timing.
