![]() To boost AP Chemistry scores further, concentrate on MC questions that assess using mathematics appropriately (SP2) and data collection/analysis (SP4), the two lowest scoring categories within the multiple-choice section.Multiple-choice: students generally scored very high on questions about Big Ideas 2 (structure & property relations) and 4 (kinetics), and least well on questions about Big Ideas 5 (thermodynamics) and 6 (equilibrium).1 student, out of ~150,000 whose exams have been scored to date, earned all 100 out of 100 points possible on this year’s exam.This is a pretty large increase in scores - the highest scores in the past 5 years – so very impressive work from this year’s AP Chemistry students.Students getting 1s/2s can usually do nothing with it to get a 3, students are usually earning >2 of the pts to get a 4: >4 of the pts to get a 5: >6 of the pts FRQ5 (polar area/tangent line) is very difficult, designed to distinguish between 3s, 4s, & 5s.Free-response questions: students generally performed best on FRQ3 (graphical analysis of f’/FTC), with ~10% earning all 9/9 points possible they generally performed least well on FRQ6 (Maclaurin series), with ~30% earning 0/9: spr.ly/6018Dlytg.Multiple-choice: students scored much higher on questions about Big Ideas 2 (derivatives) & 3 (integrals & fundamental theorem), than on questions about Big Ideas 1 (limits) & 4 (series).1 student, out of ~60,000 worldwide, has earned all 108 out of 108 points possible We'll notify her/him in late summer/early fall when we receive that data file.This is a smaller percentage of 5s than last year because a smaller proportion of students hit the standards for a 5, but as you can see, this score distribution remains exceptional.Students getting 5s are usually earning all 3 of these points: ![]() AP Biology FRQ7 (investigating sex determination in fish) best distinguished between students getting 3s and those getting 5s.Students getting 3s are usually earning at least 3 of these 4 points. AP Biology FRQ3 (investigating aquatic pollination) best differentiates between students getting 3s & those getting 2s.30% of students earned all 4/4 points possible. AP Biology students demonstrated a very strong understanding of species interactions, generally earning high scores on FRQ5 (symbiotic relationship between warblers and cuckoos).AP Biology multiple-choice: students generally scored best on questions about Big Idea 4 (interactions) and least well on questions that required use of mathematics, including the grid-ins, where 35% of students scored 0/5 points.So all score categories expanded, in comparison to 2017, except 3s. This year, there were more strong students, and more weak students – fewer in the middle.
