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.
But you could not take it more than once a month. The GRE score is valid for five years. If you take GRE more than once, the ETS will forward the most recent three scores to the schools you apply to. I am writing this to u from HYDERABAD.
