The exams are held in three mediums Sinhala, Tamil and English. The exam is the basic Certificate awarded in Sri Lanka as proof of completion of Secondary Education. The GCE O/L examination is an important milestone for students as it determines their eligibility to pursue further studies at the Advanced Level (A/L) or vocational training courses.
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [ 1 ] [ 2 ] Most thermoplastics have a high molecular weight .
In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer . [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst .
Under the recent syllabus, candidates can choose between Chemistry and ICT, although Combined Mathematics and Physics are mandatory. Combined Mathematics is a combination of Pure Mathematics and Applied Mathematics. Previously, candidates had to study these two subjects separately, but with the introduction of the Combined Mathematics syllabus ...

Most IGCSE subjects offer a choice of tiered examinations: Core or Extended papers (in Cambridge International), and Foundation or Higher papers (in Edexcel). This is designed to make IGCSE suitable for students with varying levels of ability. In some subjects, IGCSE can be taken with or without coursework.
Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, [1] is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects.
The phase behavior of polymer solutions is an important property involved in the development and design of most polymer-related processes. Partially miscible polymer solutions often exhibit two solubility boundaries, the upper critical solution temperature (UCST) and the LCST, both of which depend on the molar mass and the pressure.
