That said, there's not much out there that's better at this point. The Online Course had questions written and edited by the same people who wrote the real test. The quantity of practice tests and the similarity of the questions to real questions are the most important factors in the quality of prep material. It has been very difficult to obtain clear answers from College Board about who is writing the Khan Academy material. My best guess is that even if some of the questions are written by people khan academy sat prep write questions for the real test, the Khan material is not subject to the same selection and editing process as are real test questions, which are reviewed many times. In addition, it was possible to download every practice quiz and test from the Online Course. Khan Academy does not allow downloading of most practice questions. Only the complete tests also available from the College Board site can be downloaded. The real test is on paper. Practice should be on paper too. The delivery format of the test and practice questions makes a difference. I only recommend Khan Academy to students who need to work on basic skills and want a budget option. I agree it can be helpful to some people, but students deserve better. Here is an example of a Khan Academy reading question I find flawed. I have discussed math questions on another thread. I am mostly concerned about question 9, but question 8 is the basis for question 9, so I copied both below. You can find the relevant passage selection linked below. I took a screenshot instead of copying the passage to demonstrate a problem with the line numbering. Question 8 It can reasonably be inferred from Passage 2 that the hotspot theory A can be supported by comparing the volcanic rocks of two different islands. B has yet to be proved in part due to a lack of evidence from multiple locations. C has recently been altered after a thorough study of Hawaiian volcano sites. D won't be able to be confirmed with certainty until volcanoes get older and erode. Question 9 Which choice provides the best evidence for the answer to the previous question. Then it says that volcanoes in Kaui, far from the hotspot, are very old and eroded, while volcanoes on the Big Island right over the hotspot are much younger. This clearly shows that choice A hotspot theory can be supported by comparing the volcanic rocks of two different islands is correct. In any case, the bad style does not affect the substance of the question. Now let's come to the real issue: question 8. The less serious issue is that the line numbers in choices C 54-56 and D 59-63 do not match the line numbers of khan academy sat prep quoted sentences in the passage. I take this mistake to be serious. If it occurred on a real test, I think the question would have to be thrown out. The more serious issues concern the content of the answer choices. As discussed above, the last paragraph says that the hotspot theory predicts that volcanoes further from the hotspot should be older and more eroded. Then it says that volcanoes in Kaui, far from the hotspot, are very old and eroded, while volcanoes on the Big Island right over the hotspot are much younger. This shows that evidence from two islands supports the theory. Thus the correct line numbers justifying answer choice A are lines 55-64. khan academy sat prep These lines contain the prediction of the theory and then the evidence from two different islands consistent with the prediction. Unfortunately, these lines are not among the answer choices. We have choice C, containing lines 54-56 that should be lines 55-57 and choice D, containing lines 59-63 that should be lines 60-64. What if the rocks on the first island the one further away from the hotspot showed little erosion. What if there were no evidence from another island at all. In addition, you cannot know that the evidence from either island supports the theory unless you know the relation of the evidence to the theory. The sentence quoted in choice D presents facts about the second island, no facts about the first island, and also no explanation of the relation between these observed facts and the theory. Therefore taken in isolation from the rest of the paragraph, the sentence quoted in D does not give any evidence that the theory can be supported by a comparison of the two islands. Cheers are coming from this corner of the site as well. If that's the case, we're a pretty sad world academically. Just to finish up the discussion of the Khan reading question above: Although choice D is listed by Khan as correct, choice C is better. The theory in itself khan academy sat prep what kind of evidence can support it. D in logic for the people writing the Khan answer explanations.
