ACT Practice Test (English, Math, Reading & Science)

The ACT Practice Test (English, Math, Reading & Science) is a free 20-minute skill test from Science of Apps. It tests all four scored ACT sections — English, Math, Reading and Science — with ACT-style questions on grammar and rhetoric, high-school maths, close reading and data interpretation, each with an explained answer. Score 70% or more on its 20 questions to earn a verifiable ACT Exam Readiness certificate (SOA-ACT). Every question is based on published standards and research — including The ACT test preparation (ACT), Biology 2e (OpenStax (Rice University)), College Physics 2e (OpenStax (Rice University)) — and each answer is explained with its source.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a ACT Exam Readiness certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: The ACT test preparation (ACT); Biology 2e (OpenStax (Rice University)); College Physics 2e (OpenStax (Rice University)); Chemistry 2e (OpenStax (Rice University)). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: English (Punctuation and sentence structure, Usage and agreement and Rhetorical skills); Math (Algebra and functions, Geometry and Statistics and probability); Reading (Main ideas and details, Inferences and author's purpose and Vocabulary in context); Science (Interpreting data, Scientific investigation and Evaluating models and conclusions). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

Yes. Science is one of its four areas, alongside English, Math and Reading. ACT Science questions test reading graphs, tables and experiments rather than memorised facts, and the questions here are written the same way. From 2025 the ACT made Science optional for many test-takers, so check whether the colleges you apply to want it.

No. It is an independent practice test written to the publicly available ACT content outline, for checking your readiness before you book the real exam. Science of Apps is not affiliated with ACT, Inc., and passing earns a Science of Apps certificate rather than the official credential.
