Biology study guide: one topic explained process by process, with worked examples and exercises

Example result

Example for the Standard package

Study guide: solving linear equations, for students aged 13–14

The one rule

An equation is a balance. Whatever you do to one side, you do to the other, and the balance stays level. The goal is to get x alone on one side.

Worked example 3: the unknown on both sides

Solve 5x − 4 = 2x + 11.

  1. Move the x terms to one side: take 2x from both sides. 5x − 2x − 4 = 11, so 3x − 4 = 11.
  2. Move the numbers to the other side: add 4 to both sides. 3x = 15.
  3. Divide both sides by 3. x = 5.
  4. Check: 5 × 5 − 4 = 21 and 2 × 5 + 11 = 21. Both sides match.

Common mistake

In 3(x + 2) = 18, many students write 3x + 2 = 18. The 3 multiplies everything in the brackets: 3x + 6 = 18, so x = 4.

Exercises 7–10

  1. 4x + 3 = x + 18
  2. 2(x − 5) = 14
  3. 7 − x = 3x − 9
  4. 3(2x + 1) = 4x + 15

Answers: 7. x = 5 · 8. x = 12 · 9. x = 4 · 10. x = 6

Files: PDF and Word. The guide is for learning: we do not do homework or tests to be handed in.

Client: a parent whose daughter gets lost when an equation has brackets or the unknown on both sides. Task: a guide at middle school level that starts from the basics and builds up to those two cases. Standard package: up to 8 pages, 6 worked examples, 20 exercises with answers and a summary sheet. Excerpt below.

The client and all details are made up.

About this service

In biology the hard part is rarely one fact; it is keeping a process in order and the terms apart. This guide takes one topic at your level, such as photosynthesis, cell division or the nervous system, and explains it step by step: what happens, in what order and why. Key terms come in plain words, worked examples show how to read a data table, a food web or the description of an experiment, and common mix-ups such as mitosis and meiosis are named. Exercises with answers run from easy to harder. Tell us the topic, the grade or course, the textbook if any and what the learner finds hard. You get PDF and Word files; Premium adds a test and a separate answer key. The guide is for learning: we don't do homework, lab reports or tests to be handed in. Check terms against your course.

What is included

  • What you getA PDF and Word guide on one biology topic: the process explained in order, key terms, worked examples, common mix-ups and exercises with answers at the end. From Standard, also a one-page sheet with the terms and stages to remember; in Premium, a self-check test of 20 questions and a separate answer key with short explanations.
  • Processes in orderEach stage, what starts it and what comes out
  • Terms in plain wordsWord roots explained, so similar terms stop blurring
  • Worked examplesData tables, food webs and experiments read step by step
  • Exercises with answersFrom naming parts to explaining why, to practise and check yourself
  • At your levelMiddle school, high school, college or an adult learner

  1. 1
    TopicYou name the topic, the level and where the learner gets lost
  2. 2
    WritingWe explain the process, add examples and write the exercises

    StudyYou work through it and ask for changes within your package

What we need from you

The exact biology topic (for example, cellular respiration or the human digestive system), the level or grade, the country or curriculum and the textbook if any, what the learner already knows and which terms or stages they confuse, the language, and whether the guide is for self-study, work with a parent or a class handout. You may attach a syllabus, a list of topics or a page of notes as Word or PDF files, up to 3. Please don't send graded work, lab reports or exam papers to be solved.

We will ask you:

  • Which biology topic?
  • For what level?
  • What does the learner confuse or forget?
  • Curriculum, language and use

Questions and answers

Can the guide cover a whole biology course?

No, one topic per order, such as the basics of heredity or the circulatory system. A broad course is better split into several guides, each at the depth it needs.

Are there drawings of cells and organs?

The guide is text with tables. Where a figure helps, we say what to look for on the matching figure in your textbook; labelled drawings are not included.

Will you write my lab report or homework?

No. The guide is for learning the topic. We don't do homework, lab reports, tests or exams to be handed in as the learner's own work; the exercises in the guide are new ones made for practice.

Will it match my curriculum?

We follow the level, curriculum and textbook you name, but programmes differ in depth and terms, so the learner or a teacher should check the guide against the course.
