I hear things. On the radio or television. Random elevator talk. These bits of information can inspire observations too long for a tweet, but not a substantial blog post. Thus, the Random Thoughts category begins...
Yesterday I heard a story on my local NPR station about advanced placement classes*. The story examined the possibility that schools were expanding the population of students placed into AP work for a variety of reasons. One result would be less "advanced" AP classes, perhaps resulting in fewer students qualifying for college credit.
Both of my offspring took a number of AP courses and tests. The classes challenged them, and I am sure it looked good on their transcripts. However, these courses would not have saved any significant amount of money in college tuition.
The main advantage I see of coming in with these credits is more rapid advancement of academic rank. In other words, you obtain sophomore, junior, and senior standing sooner if you come in with these credits. This gives the student higher priority in registration for the courses that they want or need.
