In this system,I still remember that I realized to study hard in biology because I noticed that my recitations were only few unlike in first and second grading.That's why when I took the test,I really tried my best,best,best that I can to answered all questions correctly.And luckily I answered it correctly but not all.Hormones really play an important role to human's body especially in terms of production of progesterone and testosterone.Without that sex cells human race is over.Thank you........
