If you're not sure the journal is appropriate, check with me before writing the paper. Note that you are best served by getting your article several days before the paper is due. Waiting until the last minute will probably hurt you. Well, to start with, try to find something of interest to you. A second consideration when selecting the article is the length of the article.
Many students try to look for the shortest possible article.
This makes sense but should not be the only consideration. Also, some journals publish short book reviews or obituaries. These items rarely make for good summaries. Consider the content of the article when you look at the length. On this read-through, determine whether the article is really about what you expected.
