COURSES AFTER 12TH STANDARD

What are the eduacational opportunities after completion of 12th standard?


In India, we have good educational system, that is 10+2+3 or 10+2+4 system, 10th standard in various states is called as Secondary School Certificate, it is administered by different Boards, after completion of SSC, or 10th standard, a student has the opportunity to select different branches such as MPC, BiPC, MEC, CEC, HEC, Groups.  There are plenty of opportunities after completing these courses.  We have various branches for Mathematics group students and Biology group students, and there is a large opportunity for Commerce and Arts group students also.

COURSES FOR Mathematics, Physics, Chemistry students........


1.TECHNICAL COURSES:

 - ENGINEERING COURSES.....

There are various branches in Engineering.  To get admission in this engineering B.Tech, or B.E., course, one has appear for common entrance test conducted by state and central governments.  For state board, there is affiliation given by different universities.  The entrance conducted national level is JEE Mains and advanced.  When a student gets qualified in this entrance test , student is eligible for getting seat in prestigious colleges such as Indian Institute of Technology and other leading colleges.  There are secondary grade colleges also.  The student gets admission if he gets less marks.



1. Computer science and Engineering:


All over the world, each and every where computer is being used.  There is a lot of demand for computer science engineering graduates.  There are different types of sectors where an IT graduate can be placed.  The sectors include, handling projects of various companies, banking works, networking, developing website, and writing codes for a website.  Computer engineers also have the opportunity to work in government sectors such as banks, administration departments, implementing government schemes.  Developing various departments' websites, and so on.  Any fresh IT Graduate can have the chance to get amount of Rs.30,000/- a month.  An average pay scale range between 2 lakh to 3 lakh per annum for a fresh IT Graduate.

Atal Pension Yojana - Government scheme


What is cholestrol - How to reduce naturally

Concept on Cholesterol :


Where do we find the cholesterol in our body? Can you imagine, where it is found? What are the effects of Cholesterol raise in blood? When do we say cholesterol as Plaque?  Cholesterol occurs in all parts of the body, cholesterol is a waxy and fat like substance.  There is necessity of cholesterol to work properly.  But, when the cholesterol levels increased in bloody, then plaque is formed by combining with other type of materials in our body, plaque narrows the arteries, some times, plaque acts as block to the blood flow.  A small part of our body is called a cell.  These cells are built using the cholesterol.  How can a body contain cholesterol?  Larger organ liver makes required cholesterol for entire body, then how can cholesterol levels increased in our body?  Cholesterol levels are increased by over production of cholesterol by liver.  This is due to consumption of cholesterol contain foods, they are meat, chicken, etc., these are the productions of saturated and trans fat.  Who carries the cholesterol to all cells? The carriers are lipids and proteins.  Generally, they are called lipoproteins.  How many types of lipoproteins are there?  LDL and HDL.  The reasons for the formation of plaque in arteries is LDL.  This lipoprotein is called bad cholesterol.  The levels of LDL if it is high, it causes heart attack.  Why HDL is called good cholesterol?  HDL cleans the bad cholesterol, it returns the cholesterol to liver.  


HOW TO REDUCE BAD CHOLESTEROL?

What should we do to reduce bad cholesterol or increase good cholesterol?

First and important thing is changing our life style by taking good foods and starting an exercise program.  Essential thing is adding good and super foods in our diet menu.  One should consume soya products, these reduce cholesterol, at least one has to consume 1g/body weight kg.  Our daily diet should have at least one nut related food item.  Other foods are oats and barley along with fruits and vegetables.  We should see that the saturated food products should be avoided.
