The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions.
Advanced Placement (AP) examinations are exams offered in United States by the College Board and are taken each May by students. The tests are the culmination of year-long Advanced Placement (AP) courses, which are typically offered at the high school level. AP exams (with few exceptions [1]) have a multiple-choice section and a free-response ...
In February 2014 College Board released data from the previous ten years of AP exams. College Board found that 33.2% of public high school graduates from the class of 2013 had taken an AP exam, compared to 18.9% in 2003. In 2013 20.1% of graduates who had taken an AP test achieved a 3 or higher compared to 12.2% in 2003.
Both CLEP and AP (Advanced Placement) programs are offered by the College Board and offer students the opportunity to master introductory college-level work. The main difference between the two is that CLEP programs are designed to be taken without enrolling in classes, while AP exams are normally taken after completing an AP course. [13]
The predecessor to the current AP Capstone program, the AP/Cambridge Capstone Program, was initially offered in 17 high schools worldwide. With the launch of the full AP Capstone by the College Board in fall 2014, the program has expanded to now being offered in 1100 schools. [2] Over 100 colleges and universities support the AP Capstone ...
In analytical chemistry, the detection limit, lower limit of detection, also termed LOD for limit of detection or analytical sensitivity (not to be confused with statistical sensitivity), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%).
I suggest that Detection limit and Detection Limits be merged. Biscuittin 18:32, 5 July 2007 (UTC) []. Support Added templates. --Kkmurray 14:51, 19 August 2007 (UTC) []While the initial definition on the Detection Limits entry seems OK, most of the information appears to be related to the amount of material being probed, rather than a description of what a detection limit (or detection limits ...
Quality control begins with sample collection and ends with the reporting of data. [4] AQC is achieved through laboratory control of analytical performance. Initial control of the complete system can be achieved through specification of laboratory services, instrumentation, glassware, reagents, solvents, and gases.
