Until about 4 years ago I had never heard of CLEP, DSST or any other alternative credit gaining method. The beauty of these alternative testing methods is that for CLEP/ DSST all you need to pass almost every exam is a score of 50%. Yes, you read that correctly you can pass and get real college credit for a score of 50%. Where else in the world can you go spend 90 min and get the same credit as if you sat through 90 days of classes. I have personally taken and passed over 20 different exams, all on the first try.
There are 33 different exams that CLEP offers in 5 different categories. Each exam has a time limit of 90 min and covers an average of 90 question. With the exception of English (college composition) all exams are strictly five multiple choice answers per question. The exams are designed to cover all the material you would typically see in your first 2 years of college. The categories are: Business, composition/literature, foreign languages, history/social sciences, and sciences/mathematics. The complete list with the credit awarded for each exam can be found at CLEP exam list. Two important facts that you should know if you are thinking about taking a CLEP or DSST. Firstly, all exams are free for military personal and their families, this applies to all education centers on military instillation a as well as approved civilian testing centers. The military (regardless of branch will pay for your first attempt at either a CLEP or DSST , this does not mean only one exam, they will pay for as many exams as you want to take but only the first attempt, so if you fail and wish to take it again you have to pay out of pocket. Secondly there is a multitude of material out there that is designed specifically for people trying to pass one of these exams. Just to name a few things, there are study guides for each individual test, I personally used the REA study guides and had great success with them. There are also exam guides put out by Peterson's , Owl publishing and a general guide that covers all 33 exams which is put out by the test makers. All these books generally come with an exam description, study material and practice tests. The study guides can be ordered from the publisher directly but my advise would be going through Amazon or another third party site.
As for the DSST exams there are 30+ DSST exams of which 12 are upper level, meaning they will satisfy part of your 300-400 level classes should you decide to pursue a Bachelors degree in the future. My personal preference is to take the DSST exam over the CLEP exams. There are several reasons for that, the three biggest reasons are: there are only 4 multiple choice questions instead of 5, many of the exams are upper level which means they can apply to a Bachelors degree and you get a full 120 min which gives you an extra 30 min per test over the CLEP. In all other aspects DSST exams are very similar to the previously described CLEP exams. They are also funded by the military and can be taken for free. Almost all places that offer CLEP also offer DSST testing and 90% of testing locations are Internet based so you get your results instantly. As for study guides they are out there, but depending on the subject you may or may not have many options. The official partners for DSST exams is Peterson's and they offer many resources that are tailored to the tests.
If you are ready to take the leap and want to take your first exam there are a couple things you should do before you do. The first thing to do confirm with your school that they accept the credit for the exams. A complete list of schools can be found on the searchable lists of the Respective websites. Assuming your school accepts it you would secondly need to find a testing location and schedule the exam you want to take. I say schedule as the second step because you need to give yourself a deadline to meet. This will help keep you focused and on track with the next step, which is studying. Studying time needed will vary based off exam and person but on average 3-4 weeks should be plenty to learn enough information to pass. Lastly, realize you got this and that your taking the first step towards saving yourself lots of time and money.
So in closing, while this method of gaining credit is not for everyone it is certainly for some. If you have the ability to dedicate an hour a night, give days a week, to studying then you should be able to pass a class a month without any problem. So check with your schools, consult your degree programs and go get that 50%.
