Knowledge connects us all.

The fourth subject is optional, and only the part of its grade above the pass mark counts towards GPA.

A board challenge is not a re-marking — it re-checks the addition and the entry of marks already given.

A marksheet lists your subject-by-subject grades; a certificate is the formal statement that you passed.

An EIIN is the permanent identity number of an educational institution, used to identify it without ambiguity.

Fluid in the inner ear keeps moving after you stop, so the brain still reports motion that has ended.

A soap molecule has a water-loving end and an oil-loving end, and that split personality lifts grease away.

Turbulent air jostles a star’s point of light, while a planet is a small disc whose flicker averages out.

Antibiotics attack structures that bacteria have and viruses simply do not.

Half the moon is always lit — what changes is how much of that lit half we can see from here.

Fever is not the illness — it is the body deliberately raising its own thermostat to fight infection.

A mirror does not swap left and right at all; it swaps front and back, and we misread the result.

Sleep is when the brain clears waste, files memories and the body runs its repair work.
