DR. WALLACE: My daughter is in her first year at a private parochial high school. She has above average intelligence, but all through public intermediate school her grades were below average. I'm hoping that a fresh start in a different school will stimulate her to do much better academically. She is really trying, but she admits her study habits are not good. Any suggestions will be deeply appreciated. She wants good grades! — Mother, Boston, Mass.

MOTHER: Acquiring good study skills is no different than mastering any other new subject, such as algebra or French. Although successful study habits don't come naturally, there are some valuable tried-and-true study techniques that most teens can learn quite easily. I suggest you review these with her:

Taking an active approach to studying is the best beginning — just reading the assignment isn't enough! Writing causes "muscle memory." According to the book "Study Smarts," the muscles in your hand actually "memorize" what you have written. So while you read, jot down relevant topics and key phrases. But remember, if a sentence says, "There are three primary colors: blue, red and yellow," don't write down the name of the colors alone — you won't remember anything later on. It would help to also name something that is that color.

Concentration is the key to good study techniques. When you study, concentrate for a block of time. Read or study for 50 minutes at a stretch; memorize for 30 minutes. You use time better when you limit it.

Did you know that your brain works best during the day? One hour of daylight studying equals one and a half hours at night. Try to really concentrate during some daytime study periods.

Also, alternate the kinds of subjects you study. For instance, don't study science formulas after algebra; they're too much alike. Study French conjugations instead and you'll learn both topics better. After each study session, have someone quiz you — it makes you actively remember what you have learned.

However, even the best of study techniques can't always help a teen concentrate on French conjugations or trigonometric functions. But, taking a well-deserved and refreshing study break can revive concentration when those eyelids start to droop.

A cool shower offers a stimulating study break. Although a warm shower or bath usually relaxes you, a cool shower can be incredibly invigorating for even the most tired, study-clogged brain. Or briefly watch your favorite TV show. If you can turn the TV off as easily as you turn it on, a TV break can be refreshing.

Concentration requires a lot of energy, and a good way to get your second wind is to eat a piece of fruit. Fruit contains fructose, a form of sugar that is believed to provide quick energy. Exercise can also provide a much-needed lift. Exercises such as jumping rope or lifting weights get your blood circulating and boost your energy level by reminding your brain that you are, indeed, awake.

Perhaps the best way to keep drowsiness to a minimum is by setting up a schedule that alternates complete concentration with complete distraction. When studying, concentration should be total; when taking a break, distraction should be just as total.

Teachers are eager for students to learn and will assist in every way they can. Meet with a teacher if the time ever comes when you need assistance.

I'm glad that your daughter wants to earn good grades because by developing good study habits, she will succeed.
