Science classes, like biology, may be among the most challenging classes you'll ever take. Getting an A in biology means looking at some of the major issues you'll face and having tips for dealing with them.
Plan for biology study time
One of the reasons that science classes are so challenging is that they ask you to look at things you've never looked at before. When you take an English class or even a psychology class, you're often on familiar ground, adding to knowledge that you've gained from former classes or other sources.
The rule of thumb for a science class is to budget two hours outside of class for every hour that you're in class. For a class that meets five hours a week, that's ten extra hours of study time — just for that class.
Make vocabulary flashcards
Studies have shown that you learn more new words in a first-year biology class than you do in a first-year language class. That's a lot of terminology. And instructors will introduce a term to you just once and then test you on it later.
Flashcards are a great memorization aid. Spend at least one hour of your study time a week making and studying flashcards. Put the new term on one side of the card and the definition on the other side. Go through your stack and test your ability to remember the meaning of each term. When you get a card right, put it in a separate stack. Keep practicing with your other cards until you get them all right.
Your brain has two kinds of memory — short-term and long-term. Have you ever listened to your instructor explain something and thought, "Cool, I totally get that," but then later found yourself scratching your head trying to remember the details of what you learned? That's because you had the idea or process in your short-term memory but didn't get it fixed in your long-term memory.
Budget a small amount of study time every day instead of planning on big marathon sessions once a week. If you review your lecture notes on the day that you first wrote them down, while the info is still fresh in your short-term memory, you'll increase your chances of banking some of that information in your long-term memory before you go to sleep.
Study actively, not passively
Reading alone won't get most people a good grade in a science class. To store information in your long-term memory, you have to use the information actively. You can practice what you learn in several ways:
Do the activities in lab. Hands-on laboratory experiments help reinforce concepts from class— so come to lab prepared to do the experiments and ask questions!
Draw processes and structures. Take out some blank paper and try to draw the things you're learning about. Label everything and explain the concepts to yourself as you go along. Peek at your notes when you have to, but keep repeating the process until you don't have to peek anymore.
Explain things to others. If you study alone, you can explain things out loud to yourself. Or explain things to your significant other, your parents, your kids, or even your cat.
Answer questions at the back of your book chapter. Instructors often recommend questions to go along with the reading. These questions are good practice, especially the critical thinking questions that ask you to think about real-life scenarios and apply what you've learned.
Phone a friend
Study groups can really improve your success in science classes. You can practice your explanations on people who are studying the same material, ask and answer questions, and share tips and tricks with one another.
You can also support one another emotionally and maybe even make studying more fun. Many students form study groups that stay together through a whole year of classes, and sometimes even longer.
Test yourself before your instructor tests you
Before you take the test, find ways to test yourself and to identify your weak spots so you can make sure you're really ready.
Here are some tips on how to test yourself:
Some instructors actually give copies of old exams to students to practice on. Ask your instructor if she does this.
Textbooks have quizzes at the back of the chapters and often have online companion sites with more quizzes.
Maximize the easy points
Getting a good grade is about getting the best overall percentage in class that you can. Exam points are usually the hardest to get, so make sure you get all the easy — or at least easier — points, which usually come from homework assignments, labs, attendance, and even extra credit. Take advantage of every easy assignment that comes your way. Then, if you miss a few exam points, you've got back up.
Ask for help up front
Don't wait until it's too late to get help. At the first sign of trouble, like a bad grade on an assignment or quiz, get help from your instructor, your teaching assistant, the tutoring center, or a friend who's doing well in the class.
You're not supposed to be an expert on the subject; that's why you're taking the class. Sometimes, the question you ask is the one that ten other people are wondering about. Instructors and TAs are paid to help you learn, and most of them love what they do.
Use your resources
Most biology textbooks are loaded with information, and can sometimes be a bit overwhelming to read. Find out whether your instructor tests from their lecture notes, the textbook, or a combination of the two. If your instructor considers your text to be an important resource — and will test you out of the book — make sure you budget some time for reading.
One way to help you sort out and process the information in a dense biology textbook is to have a set of questions in front of you as you read. You can often find good questions in a review section at the back of the chapter, or sometimes and summary questions at the end of each section in a chapter. Instead of answering these questions after you read, answer them as you read. It will make your reading time more focused and productive.
Biology textbooks come with some nifty add-ons like access to websites with animations, quizzes, and tutorials. Sometimes, a good animation is worth a thousand words, so check out your resources and incorporate the good ones into your study routine.
If your book doesn't come with these bells and whistles, you can still find lots of good material on the Internet. YouTube is loaded with animations and even student-created songs to help you memorize something.
Be careful with materials that aren't created by a publisher or a scientist. Some homemade materials will have errors.
Don't leave it in the classroom
Research on human learning shows that people remember information best when they understand its importance. In other words, when the info is connected to a fundamental concept that's part of their existing knowledge, they remember it.
The whole point of science is to help people understand their world better. So don't leave what you learn in the classroom!
