CNA practice test: 60 original certified nursing assistant written exam questions with answers and explanations, following the NNAAP written exam content outline: activities of daily living (hygiene, dressing, nutrition and hydration, elimination, rest and comfort), basic nursing skills (infection control, safety and emergencies, positioning and procedures, vital signs and reporting), self-care and independence, psychosocial care (dementia, grief, spiritual and cultural needs), and the role of the nurse aide (communication, residents' rights, legal and ethical behavior, the health care team). As of October 2026: each state runs its own nurse aide program and chooses its test vendor (many use the NNAAP from Credentia; others use Prometric, Headmaster or a state exam), so check your state's candidate handbook. Federal rules (42 CFR 483.152 and 483.154) require approved training of at least 75 hours, including at least 16 hours of supervised practical training, and a competency evaluation with a written or oral exam plus a skills demonstration; you must pass both, and states must allow at least three attempts. Credentia says the NNAAP written exam has 70 multiple-choice questions (10 unscored pretest questions, so 60 scored) with two hours to finish, and the skills evaluation is five skills in 30 minutes, always including hand washing and one measurement skill. Our 48-of-60 target is a planning estimate, not an official passing score. Questions are original, not real exam questions. Not affiliated with Credentia, Prometric, any test vendor, or any state nurse aide registry.

Wonderlic practice test: 50 original Wonderlic-style questions with every answer explained, in five sections of ten: word meaning (synonyms, opposites, odd one out), analogies and scrambled sentences, number and letter series, math word problems (percents, rates, time, area), and logic, ordering and spatial reasoning. As of October 2026, the classic Wonderlic Personnel Test is 50 questions in 12 minutes, and the cognitive ability section of Wonderlic's current hiring assessment, Wonderlic Select (formerly WonScore), is also 50 questions with a 12-minute limit, with no calculator, dictionary or other resources. Wonderlic Select also includes untimed personality and motivation sections; Wonderlic says most people finish in about 35 minutes. Wonderlic says test takers are not expected to finish all 50 cognitive questions, that there is no passing or failing grade, and that results are weighed against the needs of the job, so each employer decides what it is looking for. On the classic test the score was the number correct, and about 20 is a commonly cited average, not an official passing score. Wonderlic also says you should never have to pay to take a Wonderlic assessment. Questions here are original practice questions, not real Wonderlic questions; the real test mixes question types and gets harder as it goes. Not affiliated with Wonderlic or any employer.

PSAT scores explained for fall 2026. The PSAT/NMSQT is scored 320 to 1520 (two sections, 160 to 760 each), and the NMSC Selection Index runs 48 to 228. When do PSAT scores come out? As of October 2026, College Board releases fall 2026 in-school scores in three waves: October 22, November 5 and November 12, depending on when your school submitted answers. What's a good PSAT score? College Board's 11th-grade benchmarks are 460 Reading and Writing and 510 Math (430 and 480 in 10th grade). We cover how the adaptive test is scored, percentiles and score ranges, how to get your scores in the BigFuture School app, reading your score report, the Selection Index formula with a worked example, and National Merit cutoffs: about 1.3 million entrants, 50,000 high scorers, about 34,000 Commended Students and 16,000+ Semifinalists chosen state by state. Cutoff figures shown are unofficial, past-year (class of 2027) numbers reported by a test prep company; NMSC sends cutoffs to schools, not the public.

How hard is the HVAC exam? It depends on your state and license level: as of October 2026 there is no single national HVAC license exam and no official national pass rate. This guide covers HVAC exam questions, HVAC exam prep and how to study for an HVAC license (journeyman, master and contractor): what the exams test, open-book tabbing skills, a study plan (our estimate), five tactics, common mistakes, three original sample questions and retake advice. One official example: Virginia's PSI candidate bulletin (dated July 2026) lists the journeyman/master HVAC exam at 85 questions in 210 minutes, 60 correct to pass for journeyman (about 71%) and 64 for master, open book with permanent tabs only; the residential HVAC exam is 55 questions, 120 minutes, 39 to pass. North Carolina's contractor board says to bring all allowed reference materials and wait 90 days to retest; Texas says its air conditioning and refrigeration contractor exams are given by PSI. Check your own state board. EPA 608 is a federal certification to handle refrigerant and does not expire; NATE and HVAC Excellence are industry certifications, not licenses. Independent guide, not affiliated with any licensing board, the EPA, NATE or HVAC Excellence. Questions are original.

HVAC practice test: 60 original HVAC exam questions with answers and explanations for contractor and journeyman exam prep: refrigeration cycle (superheat, subcooling), electrical basics, airflow and psychrometrics, heating, EPA 608 safety and refrigerant handling, and codes, load calculation and controls. As of October 2026 there is no single national HVAC license exam: licensing is handled by states and sometimes cities, with contractor, journeyman and master levels. Many states use third-party vendors such as PSI, Pearson VUE or Prometric and reference books such as the NEC, International Mechanical Code and International Fuel Gas Code, and some exams are open book. Examples only: North Carolina's Plumbing, Heating and Fire Sprinkler Contractors board says you bring all allowed reference materials and wait 90 days to retest; Texas TDLR says its air conditioning and refrigeration contractor exams are given by PSI after eligibility approval and points to a candidate information bulletin. Check your own state board. EPA 608 is a federal certification required to handle refrigerant (it does not expire); NATE and HVAC Excellence are industry certifications, not licenses.
