Your urgent problem is not my urgent problem. If you did your homework when it was issued you wouldn't be in a panic now!

Write some code then ask questions about it. The sooner you start the sooner we can help. You won't learn any Perl by getting someone else to do the work for you, but you may get a salient life lesson when you submit the code and ind it sets fire to your computer!

This is a really easy problem. A couple of hours at reading a good tutorial, such as the ones suggested above, should be enough to get you going. Please ask again once you have written the basic code if there is something that still does not work quite right or don't know how to do. We'd be glad to help you at this point.

The data part (peter, john..) it is very easy (profit links given by other monks, search also chomp and split between functions )

The headers by other hand, are formatted in a very bad way, that make the appropriate parsing difficult, at least to me. To rearrange headers you need to achieve a datastructure like the following:

[Student][]       [science][]      [total]
[]       [Roll_no][]       [Cutoff][student]
[Name]   []       [Mark]   []      [mark]
[download]

Better if you can have headers formatted differently or even if you can hardcode them into the program.

The Perl Cookbook is aged but has tasty recipes about reading from files, if i recall correctly.
