The General Knowledge Section of Success Bureau Study Material covers the complete syllabus and includes Often Asked Questions ( OAQs) in the Competitive Examinations .
Hence, you are advised to properly practice and cram the contents . You should not waste time in learning out dated books .
Below is given a small Sample of the Study Material provided to the students .
HEART : Internally, the human heart is divided into four chambers.
The function of the heart is to pump the pure blood into different parts of the body and the impure blood into the lungs for purification.
SALIVA : Saliva is alkaline in nature. It is secreted by salivary glands situated in the mouth.

KIDNEY : Kidneys filter blood. They filter the nitrogenous waste of the body from the blood and throw them out in the form of Urine.
Dialysis is used when kidneys fail to work.
Retina is the inner most layer of the eyeball.
BLOOD : It consists of :
- Red Blood Corpuscles (R.B.C.) : They contain haemoglobin (an iron compound). They supply oxygen to the body.

The defects of the Vision are :
(i) Myopia ( or short sight ) : In this, the eyeball becomes more Convex ( i.e., elongated ) and the man suffering from it can see nearer objects distinctly but not the distant ones. Remedied by use of concave glasses .
(ii) Hypermetropia (or long sightedness) : In this, a person can see distant objects clearly but not the nearer ones. Remedied by use of Concave glasses.
(iii) Astigmatism : The person can see vertical lines clearly but not the horizontal ones or vice-versa. Remedied by the use of Cylindrical glasses.
VITAMINS are natural substances present in various food stuffs. They are soluble in water as well as fat. Their deficiency causes diseases .
Infectious Diseases : These diseases are conveyed from one person to another by Viruses . Viruses are the smallest living organisms. It is almost non-living by itself. It can function and reproduce only within a living organism .
