Progesterone is a hormone released by the corpus luteum in the ovary. It plays important roles in the menstrual cycle and in maintaining the early stages of pregnancy. It may also be involved in the growth of certain cancers.
I've been following various people's posts about the GRE for 10 months now. Some people don't study at all for the GRE, some study for a weekend, the average is about 2 to 3 months, and some study for a year or more.
1 Know that a good GRE score is the highest score you can achieve after a reasonable amount of prep time (about 100 hours over roughly two to three months). 2  Take a diagnostic test as you begin your studies. You want a score that places you in the 50thâ99th percentile range (higher is better, of course). 2  That means that your goal score should be somewhere between 151 and 170 on both portions of the test.
