Biology in 30 Days
Biology is not four hundred words to memorize. It is five connected ideas, and this book teaches them in thirty days.
Biology in 30 Days is a review workbook for high school biology, grades 9 to 12. It covers the thirty highest-value topics of a standard biology course -- cells, energy, genetics, evolution and ecology -- one topic a day, taught briefly and then tested immediately.
WHAT IS INSIDE
- 30 daily lessons, each with worked examples, 14 or more practice problems, and a full answer key
- 560+ practice questions in total, plus 120 fully worked examples
- 200+ original diagrams, drawn specifically for this book
- A "Label it" diagram every single day -- 31 of them, with 172 parts to name
- A Spiral Back section at the end of each day: questions from earlier days, mixed together and deliberately unlabeled
- A 40-question Final Loop covering the whole course, with a diagnostic table that turns every wrong answer into the exact day to go back to
- Condensed cheat sheets and a 420-term glossary
WHY THE DIAGRAMS MATTER
Biology is a diagram subject, and most workbooks either skip the diagrams or reprint the same handful. This book was built the other way round. Every cell, cycle, Punnett square, pedigree, food web and body system is drawn from scratch -- and every day includes a diagram with the labels stripped off for you to complete, because reading a labeled diagram feels like knowing it, and producing the labels is the only version a test will accept.
WHY THE ANSWER KEY IS DIFFERENT
Every answer explains the reasoning that gets you there, names the mistake the question was designed to catch, and -- for the review questions -- points you back to the day that teaches it. A miss is not a verdict. It is an address.
THREE WAYS TO USE IT
- 30 days: one day per day, in order -- the full course
- 10 days: only the marked core days, when the test is next week
- One weekend: the Map, the cheat sheets and the Final Loop
WHAT THIS BOOK IS NOT
This is a review book, not a curriculum replacement. Thirty days cannot teach a full biology course from nothing, and this book does not pretend to. It is for a student who has sat through the class and needs it to stick -- before a unit test, before a final, or in the middle of a semester when the grade has started to slip.
It is also not an AP Biology book. It covers standard high school biology.
Answers are included for every question, with the reasoning that gets you there -- not just the letter.
