In 2013 more than 143,000 candidates took part in the annual NCEA and New Zealand Scholarship examinations administered by NZQA [20] and achievement results were analysed in the Annual Report on NCEA and New Zealand Scholarship Data & Statistics released each year by NZQA. [21] In 2016 more than 146,000 candidates sat NCEA and Scholarship exams.
The NCEA system has three levels – one, two, and three – corresponding to their respective levels on the National Qualifications Framework. [3] Each level is generally studied in each of the three final years of secondary schooling, [1] with NCEA Level 1 in Year 11, NCEA Level 2 in Year 12, and NCEA Level 3 in Year 13, although it is not uncommon for students to study across multiple levels.
[6] [7] A common misconception is that passing grades are only awarded to 3% of the students who sit the scholarship assessment, rather than 3% of the total Level 3 cohort. However, as evidenced by the ratio of entries to scholarship passes, the actual percentage of entries that pass is much higher than 3%.
[6] [7] [8] Quizlet's blog, written mostly by Andrew in the earlier days of the company, claims it had reached 50,000 registered users in 252 days online. [9] In the following two years, Quizlet reached its 1,000,000th registered user. [10] Until 2011, Quizlet shared staff and financial resources with the Collectors Weekly website. [11]
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
The National Certificate of Educational Achievement, the current national secondary school qualifications, uses standard-based assessment.Assessment for Achievement Standards uses a four-grade system, the lowest being a failing grade, while Unit Standards use a simple achieved/not achieved (pass/fail) grade system.
In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
