There are three questions that I'm often asked by my students in general, about Astrology and the future. The first question is always about the Cusp of the Year, or the eight points around the year. My answer is, it changes from year to year.
For me, the real challenge is not being able to predict the end of the year Astrology, or predicting the end of the century, in advance. The question that comes to mind as we sit and wait for the September session to end is, "How can I know how much longer the session will last?"
The second question that comes to mind as we sit and wait for the September session to end is, "How can I know how much longer the session will last?" and the answer is, you can't, and the only way to know the answer to either question is to do your own Astrological study.
I've been studying Astrology for a long time now and I have to tell you the AP Biology Exam Change is not the best place to study Astrology. So, let's talk about when did the AP Biology Exam Change, if indeed it did?
All of the Biological Sciences test at the same time each year. The only exception is in the Biology of course, which is run in sections, meaning it can vary from year to year.
And each section varies in it's own way. For example, the Life Sciences Exam is very easy because there are two (2) sections. The first section is the Test of Basic Knowledge and the second is the Test of Scientific and Technical Communication. The Test of Basic Knowledge is done through your response to questions in your book.
The questions on the Test of Basic Knowledge have questions that are very simple, such as "Did you know there is a difference between the way the night sweats and the heat sweats? "and the questions on the Test of Scientific and Technical Communication have questions that can be quite challenging, such as" Do you know that you can get a headache or upset stomach from sitting near a phone with too much radio waves?
And what about the Biology Exams? They are always the same.
The Biological Sciences Exam is usually the same, so it's not a good place to study Astrology. So I don't think that I can give you an answer to when did the AP Biology Exam Change.
The answer for your question should be, it doesn't matter when I studied Astrology, because when I studied Astrology I studied the Biology Exams. There is no other place that I can think of where I could study Astrology that has the other two Exams.
