Start with your college’s rules
Two placement tests you are likely to meet at a US college are ALEKS PPL and ACCUPLACER, and some colleges accept a GED score instead. Each test is the same product everywhere, but the rules around it are not. Each college chooses its own cut scores, how many attempts you get, how long you wait between them, and how many hours of practice you must log first. Three colleges using ALEKS PPL show the range:
| College | Attempts | Practice required before a retake | Wait between attempts |
|---|---|---|---|
| Harper College | An unscored preview, then 4 proctored | 3 hours before the 2nd proctored attempt, 5 more before the 3rd, 8 more before the 4th | Not twice in one day |
| University of Rhode Island | Up to 5 | At least 5 hours in the modules | 24 hours |
| Florida Atlantic University | 5, all proctored | None required; 10 hours recommended | 48 hours |
Your college’s testing page will have its own version of this table and its own score chart. Read both before deciding how to treat your first attempt: where attempts are plentiful and the deadline is far off, a first sitting costs little and tells you where you stand; where you have one or two, prepare first.
How ALEKS PPL works
McGraw Hill says the ALEKS PPL placement assessment uses “25 questions or less” to cover 314 topics, with open answers rather than multiple choice, and comes with up to five assessment attempts and 12 months of access to a learning module. The University of Rhode Island explains the result as a number from 0 to 100, the percentage of topics ALEKS judges you to have mastered, and notes that ALEKS gives you an on-screen calculator only on questions that need one.
Between attempts you work in the Prep and Learning Module, which builds a path through the topics you missed. McGraw Hill says students who study for six hours in it raise their placement by at least one course; that is the vendor’s claim, not an independent study. ALEKS’s support pages say its learning mode also runs knowledge checks: after 20 topics learned and 5 hours of work, after 10 hours, or after 60 days without one. A topic you miss in a check goes back into your learning path to be practised again, so expect some of your progress to reappear as work to redo.
How ACCUPLACER works
ACCUPLACER has three math tests: Arithmetic; Quantitative Reasoning, Algebra, and Statistics (QAS); and Advanced Algebra and Functions (AAF). Your college decides which you take and what score places you where, according to the College Board’s program manual, which also gives each test as 20 adaptive questions, all multiple choice (unlike ALEKS’s open answers), with a pop-up calculator on some of them. There is no time limit, and each test is scored from 200 to 300. The three tests climb in level, so find out which one you are sitting before you decide what to prepare.
Coming from the GED
If you are taking or have passed the GED, your math score may matter more than a placement test. The Mathematical Reasoning test runs for 115 minutes in two parts. The short first part allows no calculator; in the second you get an on-screen TI-30XS, and a formula sheet is provided. GED Testing Service’s guide for educators puts the content at roughly 45% quantitative problem solving and 55% algebraic, so the algebra deserves more of your time than the arithmetic.
Scores run from 100 to 200, and 145 passes. On the GED score scale, 165 to 174 is “College Ready”, and GED Testing Service says students in that band should qualify for waivers from developmental courses and from applicable placement testing. 175 and above is “College Ready + Credit”, which, depending on the program, may earn up to 10 college credits, 3 of them in math. In both cases the college decides, so ask its admissions or testing office whether it honours them. If college is the reason you are sitting the GED, the extra preparation it takes to move from 145 to 165 may save you a placement test and a developmental course.
What to study: the same skills, one layer up
Placement tests at the algebra level keep asking the questions you met with numbers years ago, now with letters in them. Take 1/3 + 1/4: over a common denominator of 12 it is 4/12 + 3/12 = 7/12. Now take 2/(x + 1) + 3/(x − 2). The common denominator is (x + 1)(x − 2), the top becomes 2(x − 2) + 3(x + 1) = 5x − 1, and the answer is (5x − 1)/((x + 1)(x − 2)). It is the same procedure.
Our prerequisite map lists the first as a direct prerequisite of the second: adding fractions with unlike denominators sits immediately under adding rational expressions (unlike denominators). When a rational-expression question goes wrong, try the number version. If that goes wrong too, the fraction skill is what to fix, and fixing it repairs a whole family of algebra questions at once. Working backwards like this from each wrong practice answer is slower than doing more practice tests, but it turns practice into a list of what to study rather than just a score.
A study plan that fits a deadline
Work backwards from your college’s deadline. First, a diagnostic: a practice test, an unscored preview if your college offers one (Harper does), or a scan like ours. Second, repair the lowest gaps it finds, oldest first, because each fix makes the topics above it quicker. Third, in the last stretch, practise in the format of the real test, and keep coming back to the topics you fixed early on so they are still there on the day. If the gaps reach right back to arithmetic, learning maths from scratch sets out the order the earlier material comes in.
