GED Science Complete Prep: 50 Full-Length GED Science Practice Tests + Comprehensive Study Guide

A science question can ask you to make sense of an unfamiliar experiment even when you already know the vocabulary. This instant downloadable PDF gives adult learners a place to practice that work: reading the evidence, noticing what changed, and deciding which conclusion the results support. Reza Nazari brings the lessons and practice together in one study guide, with explanations you can return to after a difficult question.

50 distinct tests

Ten in the book and forty additional online.

Three science areas

Life, physical, and Earth and space science.

Answer explanations

Follow the reasoning behind practice answers.

Instant PDF access

Read on a device or print study pages.

What You Get Inside

The book includes a science study guide, worked questions, chapter practice, vocabulary support, quick review, ten full-length practice tests, answer keys, scoring guidance, and detailed explanations. Its online access pages lead to forty additional tests. The ten printed tests also have matching online companions; those companions are the same forms, so the total remains fifty distinct tests.

Each practice test has 34 questions. You can use the book to review a single skill or work through a complete form. Questions ask you to read passages, examine graphs and tables, interpret scientific models, and use quantities supplied in a problem. Some responses call for a calculation or a structured answer instead of choosing one letter.

Support for the Work Between Tests

Worked reasoning

Guided questions show how a passage or result supports an answer. The explanations address the details that matter in that question.

Chapter practice

Check a topic after studying it, then consult the explanations at the back of the book.

Data and graph practice

Read axis labels, compare observations, and distinguish a measured result from a claim about it.

Review before a test

Return to the vocabulary and quick-review material when a missed question exposes a gap.

A Study Routine You Can Repeat

Begin with a test if you want a record of where you are starting. Mark questions that felt uncertain, including ones you answered correctly. Then study the relevant lessons and attempt their practice questions before reading the answers. After reviewing an explanation, try stating the reason for the answer in your own words. A later test gives you another opportunity to use that reasoning with different evidence.

You do not need to finish a chapter in one sitting. A tutor can use one graph or investigation for a short lesson; an independent learner can keep notes on the evidence they missed and return to those notes before the next practice session.

Science Topics and Reading Skills

  • Life science: cells, body systems, genetics, ecosystems, and relationships among organisms.
  • Physical science: matter, chemical reactions, energy, forces, motion, and electricity.
  • Earth and space science: Earth systems, weather, climate, and the universe.
  • Scientific reasoning: experimental variables, fair comparisons, evidence, conclusions, and quantitative information.

The reading practice matters across these topics. An unfamiliar setting still gives you information to work with. Pay attention to the question’s task, the units in a table, and the comparison a researcher actually made.

Why Choose the Instant PDF?

Read and revisit

Open the file in a PDF reader and return to a lesson while reviewing a test. Internet access is needed for the linked online materials.

Print for your study time

Print the pages you need for your own study, subject to the publisher’s copyright terms. The 320-page eBook includes its front and back covers. This purchase supplies a digital file; a physical book is not shipped.

Is This the Right Book for You?

A good fit

This resource suits adults preparing for GED Science who want topic review and repeated practice. Tutors and adult-education instructors can use it to plan individual study sessions.

Additional support to consider

Learners who need extensive instruction in basic reading or arithmetic may need that support alongside the science work.

The book is an independent preparation resource, with original practice questions. It is not sponsored, endorsed, or approved by GED Testing Service or ACE.

Common Questions
