CBSE Class X Result 2010 – How to Calculate Percentage

Today, CBSE Board, India declared class X result for year 2010. But here is a catch – this year they changed the rating from numbers to grades. Most of the students are apparently confused how to get percentage from their GPA.

How to convert CGPA to Percentage

Here is the simple method to  convert GPA into percentage:

Percentage = 9.5 × CGPA

Example:

CGPA = 6.8

Percentage = 9.5 x CGPA = 9.5 x 6.8 = 64.60%

The percentage calculated by this manner is the overall percentage.

How to convert GP to Percentage

Here is the simple method to calculate percentage from GP:

Percentage = 9.5 x GP

Example:

GP = 06

Percentage = 9.5 x 6 = 57.6%.

The percentage calculated in this manner is the percentage in that particular subject.

The magic number 9.5:

The number 9.5 in the percentage calculation is not a magic number. This is derived using following formula:

Percentage = (10 x GP) - (GP/2)

Percentage = GP(10 – 1/2)

Percentage = GP(9.5) = 9.5 x GP.

 

Hope this will clear students confusion.

Redirecting to new window in c#

As a developer, many time I wished to redirect user to a new URL into a new browser window. I wanted to use response.redirect at server side and open the new web page into a new window. But the way redirection works makes it impossible to open a new window from server side. The common solution to this problem is to use java script's window.open statement at client side and then fetch the new URL into the new window. To me, this is totally unacceptable while I am writing server side code. So I decided to write some code to do this. But before writing, I googled for the same.

As they say a code worth one thousand words, here is the code: ResponseHelper Class: The ResponseHelper class does all the magic. It adds a client side script to the response which opens the new window. Use this class in place of response class if you want to open new window. Yo
