    1. Calculate the mean for the following data points:
    55, 87, 71,38, 19

    2. Which of the following is NOT characteristic of metals?

    3. Heat generally

    4. What is NOT a good strategy for approaching charts, tables, and graphs?

    5. Scientist experiments to see if acids affect the health of a particular type of plant. Three sets of plants were treated with acidic solutions of a pH of 2, pH of 4, and a pH of 6, while the control set was treated with a solution of neutral pH 7.

    Results of the experiment:

    1. Plants treated with a pH (2) - 10/10 plants are dead
    2. Plants treated with a pH (4) - 5/10 plants are dead
    3. Plants treated with a ph (6) - 2/10 plants are dead
    4. Plants treated with a ph (7) - 0/10 plants are dead

    Which is the best conclusion for this experiment?

    6. Most of the nervous system response inside of your body is not in your control. True or False?

    7. Read the text and finish the sentence below the text.

    "Inheritance is the process by which genetic information is passed on from parent to child. This is why members of the same family tend to have similar characteristics. Inheritance describes how genetic material is passed on from parent to child. Most of our cells contain two sets of 23 threadlike structures in our cells, made of a long DNA molecule, wrapped around a protein scaffold. Humans have 23 pairs of chromosomes, they are diploid.

    Each of the cells in the new person contains genetic material from the two parents."

    10. A tall man feeds his cows different amounts of food each day. He notices that the cows are happier on days when they receive the most food. In this situation, what is the independent variable?

    11. Emma experimented to determine if an individual’s pulse would be affected by listening to different kinds of music. She hypothesized that a person’s pulse rate would change if they listen to different music types. All persons were listening to 7 different types of music for 30 seconds. The pulse of each person was taken right before the music and also after the seven 30-second intervals of music. So after the music sections were completed, their pulses were taken again. Based on her experiment, Emma came to the conclusion that an individual’s pulse rate was changing when they listened to different kinds of music.

    In Emma’s experiment, what component is missing?

    12. The area of the United States where tornadoes are most frequent is called

These practice tests are part of our GED online prep.

Taking practice tests is very important because they indicate what your knowledge gaps are.

It’s important that you know what your weak points are so you can focus on learning these topics.

Recent GED graduates have some good advice for you: don’t try to learn for all four GED tests at once.

You are allowed to take one of the four GED tests at a time, so prepare for one subject area, take that test, and move on to the next subject field.

When preparing for the GED test, the most common slipup is forgetting to block some time for learning.

Postponement and pretexts are your biggest enemies. Please adopt a learning schedule and stick to it.

The second common mistake that leads to failing the GED test is the fact that students spend too much time on one question and end up not making it through the whole test.

Time management is one of the biggest stumbling blocks to passing the GED test.
