If I got around a 33/46 on the FRQs, how likely is it that I got a 5 on this year’s chemistry test? 4/4 Q4 A student investigates various dyes using paper chromatography. Here are some additional resources to help you prepare for AP exams this spring. This is not a big deal I would hope and it looks like most things came down to basically single concept plug and chug problems except for the couple of conceptual items. I am projecting an 81/100 so that’s like borderline. Does anyone know if the late AP Chem exam given today, May 18th, will be posted anywhere? AP Chemistry Exam Past Papers. The word form person that graded Q1 is that is was NOT accepted. Josh, I’ll quote Paul C., and his comment below. In fact, honestly, there were not many real world context problems here. Your email address will not be published. I would not accept that answer to 3d, and don’t expect that it will be accepted. The grade boundaries are set with the MCQ in mind too, so it’s a complicated beast, especially in the wake of the new exam. Like I can’t stress that enough. GO ON TO THE NEXT PAGE. For 2(e), do you think it will be ok if students calculated several values of ln[CO(NH2)2] vs time and found a consistent slope? Your students are a lucky group. no, that’s not accurate. Many students scoring 4s and 5s will likely attend schools with more rigorous chemistry sequences (and sadly, they will likely forfeit their credit). Also, assuming that you found the +1 formal charge on the nitrogen, then SOME other atom had to be negative. There are several things on the SAT that are not on the AP, and secondly, don’t think that preparing for one is the same as preparing for the other – it isn’t. But when you only get 2 points on a 10 point question, I wouldn’t consider that great. Dingle — Is the SAT Chem Subject exam similar to the AP Chem exam? It may or may not cost a point, but just don’t do it! There have been many problems like this in the past, where the LDF’s of the much larger, but non-polar CCl4 molecules, outweigh the LDF’s and dipole-dipole IMF’s of the much smaller, but polar, HCl. Much easier than last year, in my opinion. In d(i) don’t put hydrogen bonding! I have now edited to give the consistency. Oh and I talked about how in one of them the dipole moments cancel out and they dont in the other (Idk if thats right tho but it was kind of after I explained everything so it wasn’t my main argument). Aced the sh*t out of it. I don’t understand why you are subtracting one of the cell potentials for 7c part a subpart i. And keep in mind Nina that those cut lines were for the International Exam… Have no idea what the cutlines for the Operational Exam were, I hope the curve is enough for me to get a 5. There goes my 5. If the person with the fever must take another pill when 2/3 of the first pill has decomposed, how many hours should she wait to take the second pill assuming that the pill is effective after 30 minutes?”. Only time will tell. Just took my AP Calc exam. 3c – I imagine that once the net ionic equation has been written, simply pointing out that when a weak acid and its conjugate (as shown in the equation) are present, the solution is a buffer, would be sufficient without discussing limiting factors. beginning of content: Free-Response Questions. I would love to know more about this. They want “storytime” context, and “real life situations”. So can you explain to me how you approached the problem? I already gave my teacher an earful. 45-63 = 3. Download free-response questions from past exams along with scoring guidelines, sample responses from exam takers, and scoring distributions. All the same, I hope you get the score that you want, buffers notwithstanding! I’m retaking the Chem exam next year and actually going to study buffers this time. About 80% of the people I’ve spoken to on Reddit agree with me (and I’m under the assumption they actually learned it well ~~ unlike me). That’s a shame. Many, many, many words. It was so fkn stupid how they threw me off with a buffer problem. In (a) a ton of people that CAN calculate formal charge will not get the point about negative charges residing on more electronegative atoms. Class of 2025 Early Decision Notification Dates. The prompt says “no reaction is OBSERVED to occur.” That does not mean that there are no collisions with sufficient energy, just that there are too few to produce an observable reaction. Freaking retarded question. With AP exam dates less than a month away, it’s time for students to prepare for these intensive tests. Thank you for all of your work and sharing with us! Both this questions where LDFs dominate and acid/base buffers are on the exam every year. Good call. A more rigorous college general chemistry exam may have more of the structural/conceptual questions (and maybe even questions on orbitals), more “tricky” questions or even multi-concept questions (like they may be asked to relate thermodynamic data to pka). now I got the buffer one completely wrong and the easiest question completely wrong. There is no need to go beyond octets to seek “better” formal charge. thanks. Thanks Adrian. Ignore the 10 statistical questions, and grade the remainder out of 50. so 10 of the questions are just for statistical purposes? Buffers are one of the harder topics in AP chemistry in general, but many kids will do fine. Just Admit It: What’s Going on With Standardized Testing? It was presented as if its insignificant. Few of these offer complete tests in the same format as the real exam, but they do provide a large repository of practice questions (mainly multiple-choice). I don’t agree. It’s important to perform well on the exam, as colleges will want to see your scores and that you understand the material – especially if it’s in a course that relates to your areas of interest. I was actually pretty suprised at how straightforward and approachable most of the problems were. All I need is closure on the damn buffer problem. Almost impossible to do without seeing the MCQ’s, and in the light of the instability of the new exam. In the days and weeks leading up to AP exams, make sure you’re familiar with the test format, what questions will be asked, and, of course, the content. 64-78 = 4 No, it need not tail into the x axis. shouldn’t the 30’C tail into the x-axis prior to reaching the activation energy? Thank you! Like I didn’t know what to do. As Byron says, that is an entirely appropriate buffer question, predicted by me, that is 100% in line with the AP curriculum, and as such it is VERY fair. If I estimate that I got 50/60 right on the MC, what would my x/50 be? For sure. I might be in the minority here, but I find buffers quite interesting in how they work. That counts as 5. As you have said repeatedly there are some kids not prepared to even take AP Chem, but there are also some % that are prepared and just have teachers that don’t know what is tested, which is a shame. The questions are here. You’ll be fine and I probably will too, as I kind of feel like I will get around an 80% as well. Shouldn’t the cell potential be 3.10 V? In all fairness, though, all students in AP chemistry at my school have taken honors chemistry the preceding year, so we have more time than many other teachers do. This can go a long way toward cutting back costs and allowing you to bypass entry level courses your freshman year that might not be engaging or challenging since you already know the material. I said, “On a recently administered new exam, it was 79”. Is it like the way the question is asked that is different or additional content?
