The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement. It is the only system of measurement with official status in nearly every country in the world, employed in science ...
The luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 5.4 × 10 14 hertz and that has a radiant intensity in that direction of 1 / 683 watt per steradian.
"The metre, symbol m, is the SI unit of length. It is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit m s −1, where the second is defined in terms of ∆ν Cs." [1] 1 / 10 000 000 of the distance from the Earth's equator to the North Pole measured on the meridian arc ...
[a] This system underlies the International System of Units (SI) [b] but does not itself determine the units of measurement used for the quantities. The system is formally described in a multi-part ISO standard ISO/IEC 80000 (which also defines many other quantities used in science and technology), first completed in 2009 and subsequently ...

The School Leaving Certificate, commonly abbreviated as SLC, [1] is the final examination of Class 11 and Class 12, which is also known as the +2 course in Nepal. [2] The +2 course is generally pursued after completing the Secondary Education Examination (SEE) (Class 10 Final Exam).
Secondary Education Examination (SEE) is the final examination in the secondary school system of Nepal which is being taken by National Examination Board .National Examination Board upgraded from what was previously known as School Leaving Certificate (SLC).
Secondary schools (form 1–5, age 11 to 16) At the end of form 5, a student has the option to sit O-levels. Success opens the option to spend two years in 6th form, where a student may sit A-levels and Intermediates. A-levels are more difficult than Intermediates but both are needed to advance to the next level of education, which is university.
