I skipped 7 and got at least 60 of them wrong. Does anyone think I could still get a 700? 
To be serious, I feel that I should have at least 50-60 correct. I would be surprised if I got anything lower than 650, but I’m crossing my fingers for at least 700.
@xxjmodxx as pth goes up calcium goes up. Read any textbook.
All in all, that definitely wasn’t a bad test. Could have been worse. RIP to the Saturday nights I spent studying Barron’s plant hormones, reproductive systems, and every little endless detail about the circulatory system. So much wasted time.
That being said, it wasn’t great, either. The test was more logic based, which was good, but it was logic that no one has ever heard of. What in the world was that mountain question?
@xxjmodxx That would contradict with the graph. In regards to the reference of feedback, take oxytocin for example. It basically widens a woman’s vagina when she is having birth. That is a positive feedback. A stimulus calls for the intensification of that hormone secretion. In PTH, low calcium levels do not call for less PTH to lower its calcium levels, therefore refuting positive feedback. It is negative feedback because low calcium levels in the blood stimulate parathyroid hormone secretion, whereas high calcium levels in the blood prevent the release of parathyroid hormone. This may be a little confusing. So here are some definitions:
Negative feedback mechanisms maintain dynamic homeostasis for a particular condition (variable) by regulating physiological processes, returning the changing condition back to its target set point.
Inversely, positive feedback mechanisms amplify responses and processes in biological organisms. The variable initiating the response is moved farther away from the initial set-point. Amplification occurs when the stimulus is further activated which, in turn, initiates an additional response that produces system change.
So, as you can see, the juxtaposition of the graph and “negative feedback” was really confusing. But you have to remember that negative feedback is regulation and positive feedback is amplification. Blood calcium levels were “regulated” by the inhibition of PTH secretion when calcium levels got too high. Hope this helped.
@ObitoSigma Same here! I skipped 7 or 8 and the ones where they give you the charts and graphs killed me (the graphs and charts were confusing). I’m just striving for a 700, but you have to score a 61 in order to get that… I wished the test focused more on genetics and evolution and then the last 20 questions either went more in depth with genetics or evolution (E or M).
It is important to note that on the sensory/motor neuron question, the sensory neuron was FROM the gallbladder, the Motor neuron too it. So, if the sensory was cut, the GB would still get signals, just not send them out.
motor ftw
@HawaiianHost well the answers in my opinion were as follows: as pth increases pth increases. As pth increases calcium decreases. And at 50 the body will do processes to return the amount of calcium.
Or possibly the reverse… All I remeber is that whatever the first question was the pth mirrored the decrease or increase and then the calcium did the opposite of that.
I think that the thing that I got wrong in the calcium is that calcium is an independent variable. I know that that question has been discussed a lot. I still think that the mud is density though
The thing is that if calcium is high, then pth will go down as it is not needed. I got that wrong because I didn’t know what pth was and I didn’t give much thought to the fact that calcium is independent.
exact same thoughts. barron’s tests are a lot easier and more content-based.
What do you guys think is the most you can get wrong to get a 700?
^thanks
Was last year’s test easier? One of my friends told me they they took it last year (who didn’t do very well in bio) and thought it was hard but got a 760.
@AnniiT I don’t know about last year’s, but personally I think this one was easier than the Blue Book 2011 official practice test in most ways
@boltingflame many have been saying they only missed about 2 or 3 and are upset about it where I skipped like 7 questions and missed 8. I might either retake it next year or not send this test to colleges.
@nickly how many practice tests for each subject test are in the book? I regret not buying the blue book lol.
I think that I skipped like 6 and so far, I got like 8 wrong…and if anyone has an official conversion chart, please pm it to me.
I omitted three, definitely 6-8 wrong it appears at this point. Hoping for the best! I desire a 750 or above.
Does anyone have the chart? If so please post or pm me.
