web applications - An idea which would reduce small calculations.How to implement it? -

if wrong question pose on site please let me know.i can't find better site. i'll grateful if can suggest few sites/forums,to post question.

i have idea & see in action.

i in 2nd year of graduation. our semester marks on our college website. have around 7 subjects , 7 rows on results page. cropped 4 rows in pic below.

the thing total of subjects & percentage aren't displayed on page .we need open calculator on our pc , manually type in marks add them , our grand total , calculate percentage.

my idea reduce trouble in tedious task. so, thought of making student total marks & percentage in single click without such manual entry work. i'd design plugin or app (i'm not sure how address problem).

my question found ways of doing this: 1)scanning source code of page & find marks. 2)by plugin or app. (i'm not sure how it!)

i window popup on page single click & display total marks & percentage.

how can solved?? plugin or anything?? people access site pc mobile phones .so compatible both devices feel !!! u say??then how achieve ??

another thing noticed upon selecting marks results table, subject names getting selected , how seperate marks selected text.(in case if need select text in solving problem).

my college has around 3000+ students , quite number of students use it.

i'm doing major in computer science , , love build on own.i know c,c++,java ,some html/css of now.i'm interested in learning new things done!

thanks reading this! need in letting happen.

if using linux, can achieve simple bash script :

• wget webpage containing result table.

• parse using kind of parser extract information want, in case marks , credits.

• finally got define simple function calculation you.

good luck.
