The Civil War and Reconstruction (DANTES)

The DSST Civil War and Reconstruction exam is recommended by Prometric to be worth three upper-level humanities credits, though many schools put it in a separate "Social Sciences/History" category. This is one of the more comprehensive history exams that I have taken, but it can easily be studied for and it's one of the more interesting subjects I have studied.

The first resource that you ought to use--and the resource I found I remembered most of the facts from when writing the exam--is the DVD box set of the Public Broadcasting System's The Civil War - A Film by Ken Burns. This is probably the most comprehensive documentary on the Civil War made to date, and tells the story of the war largely through the primary documents from that era such as speeches, letters, and so on. Any American university or public library worth its salt should have these DVDs available for borrowing, and if they don't, you should ask them why. Watching the entire DVD set once should give you a firm foundation for writing the exam; watching it three times is even better.

For some extra video material besides the Ken Burns DVDs, there are free video lectures from Yale University on the subject of Civil War and Reconstruction available. Also, Annenberg Media offers some relevant videos in its series, A Biography of America, located at Learner.org. Videos 9 - 12 are all relevant to the study of the Civil War. Despite being shorter than the Ken Burns DVDs, they still have some additional useful content, and you'll know more going into the exam after watching these videos and the Ken Burns ones than if you watch the Ken Burns series by itself. To watch these, you'll need to sign up for an account at Learner.org, which is free to do.

I suggest mixing up reading with watching the video materials so that you don't get bored from doing a single form of study all the time. The U.S. Department of Education offers a list of free resources on the Civil War here, and it's worth reading through them during your studies.

You should know about the different battles of the Civil War (memorize which commanders were at each battle for both sides; this is important), and leaders of the Civil War (when you open this link, click on the thumbnails to learn more about each person, and visit Wikipedia to get any additional information on them). There's also a good timeline of the Civil War available from the Library of Congress.

Some specific facts you ought to know are that more troops died of disease in the war than anything else, the total number of troops who died during the Civil War was around 650,000, the bloodiest battle of the war was Antietam, the first battle was at Fort Sumpter, the slave-holding states which remained in the Union instead of joining the Confederacy were Missouri, Kentucky, West Virginia, and Maryland. You'll pick up a lot of these facts by watching the Ken Burns DVDs.

Note that the title of the exam says, "and Reconstruction." You'll need to know about what happened after the war, as well, for which I strongly recommend reviewing the Reconstruction Timeline on George Mason University's website and reading up on each event mentioned in it.

If you study all of these resources, you should have no problem passing the DSST Civil War and Reconstruction exam. Good luck!

DSST Principles of Physical Science I Exam Guide (Physics)

Let me begin this guide by saying that I only ever took the mandatory science classes in high school--that is to say, the most experience I have in science courses was taking a Grade 10 general science class. That said, the DSST Physical Science I exam is one of the easiest exams I have ever written.

According to the DSST fact sheet, the exam consists of 60% physics and 40% chemistry. If you intend to write this exam, simply study the general concepts in those areas and know how to apply some of the related formulae, and you should be able to pass the exam.

There's a lot of stuff mentioned on the fact sheet, all of which you should look up and study, so I'll just give a few examples and relevant links here to get you started.


PHYSICS

Check out Wikipedia's entry on elementary physics formulae. Many of the formulae aren't important, but you should know things like work, force, distance, power, time, energy, acceleration, and gravity. You should be able to comprehend how these various elements may be related to each other in terms of formulae.

Know the relation between distance and gravity/magnetic forces. In other words, know how it's an exponential inverse equation.

Study vectors and direction.

Understand the basic ideas of the laws of thermodynamics, particularly the law of conservation of mass.

Know the difference between potential and kinetic energy.

Know Ohm's law, which says that Voltage equals Current multipled by Resistance (V = I * R), and the other variations of it (I = V/R, R = V/I). You should be able to do basic calculations with Ohm's law. You should also be able to remember the electrical formula for power, P = V * I.

Know the various SI units and scientific notation.


CHEMISTRY

Understand the basic equations of specific heat. You should be able to do basic calculations involving mass, heat energy required, etc. There is an example of one of these questions on the DSST Fact Sheet. There is also a good video on specific heat calculations here:



Know the different states of matter. One of the more important things to remember about the different states is that a liquid is incompressible.

Know the difference between chemical and physical changes and be able to evaluate changes and determine which kind of change it is.

Those are all of the tips I have for studying in this guide, but they're not all of the things you need to know. Be sure to read the DSST fact sheet on the subject and study any additional points not mentioned here before writing the test. Good luck!
