General chemistry (sometimes referred to as "gen chem") is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. [1] The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out ...
In August 2018, Ofqual announced that it had intervened to adjust the GCSE Science grade boundaries for students who had taken the "higher tier" paper in its new double award science exams and performed poorly, due to an excessive number of students in danger of receiving a grade of "U" or "unclassified".

The 3 core sciences namely Biology, Chemistry, and Physics will be updated for first teaching in August 2023, with first examinations in May 2025. The syllabus change was originally scheduled for 2021, though the COVID-19 pandemic caused the IB to delay the syllabus change to 2023.
In many American medical schools, an integrated curriculum refers to a non-compartmentalized approach to basic science learning. As opposed to traditional medical curriculum, which separate subjects such as embryology, physiology, pathology and anatomy, integrated curricula alternate lectures on these subjects over the course of the first two years.
LibreTexts' current primary support is from the 2018 Open Textbook Pilot Program award from the Department of Education Organization Act.

In organic chemistry, neighbouring group participation (NGP, also known as anchimeric assistance) has been defined by the International Union of Pure and Applied Chemistry (IUPAC) as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma or pi bond contained within the parent molecule but not conjugated with the reaction centre.
The unit of r(T) can be converted to mol⋅L −1 ⋅s −1, after divided by (1000×N A), where N A is the Avogadro constant. For a reaction between A and B, the collision frequency calculated with the hard-sphere model with the unit number of collisions per m 3 per second is:
