comment Rendering percent symbol in the correct typeface
@Jens, you can set this globally using SetOptions[Graphics,BaseStyle -> {PrivateFontOptions -> {"OperatorSubstitution" -> False}} ] or SetOptions[$FrontEnd, PrivateFontOptions -> {"OperatorSubstitution" -> False}]

comment How can I improve my code with efficient mathematica built-in functions?
This still isn't a minimal working example: I can't see a definition for rk. If you have a separate function for it, you probably shouldn't have it as a local variable inside the Module. May I also point out that completely changing the variable names half an hour after posting the original question makes it quite difficult for people who are trying to answer the question to keep track. I would also recommend against using single capital letters as variable names (V etc) as they are often reserved for use as system symbols.

comment How can I improve my code with efficient mathematica built-in functions?
I edited your program to remove the Subscript constructs, which just make it harder to read on a web page. The short answer to your question is "yes, you can use these other functions like FoldList, and yes, you should". However, without knowing what data and func1 are, it is a bit hard to work out code to actually implement what you want to do. Similarly, how does one get a[0] etc? And what are m and n? Please post a minimal working example so that people can help you.

comment defining recursively a function with multiple if conditions
You need to define a starting value for A[x,0,l], and memoize your function, I think.

comment Graphics exported from Mathematica 9 are very large because even standard fonts are embedded
It's worth noting that the PDF/A standard requires even those standard fonts to be embedded. But it's possible they aren't being properly subsetted?

comment Making fractals with Mathematica
Dear @RichardTodd, welcome to Mathematica.SE! You have made a good suggestion, but it wasn't really enough to be a separate answer. I know this might have been because you don't have enough reputation to comment yet. If you have code you can post, to complement your comment, you could post that as an answer, together with the explanatory text that I have converted into a comment. Once again, welcome and thanks for your contribution!

@NoEscape - that question exists already on this site.

What criteria would you use to assess the second bullet point?

comment Show Legend with 3D ListPlot
More to the point, there is an example of a ListPlot3D in the PlotLegends documentation that shows how to use ShowLegend in that context. The main trick is to include a second argument to instruct ShowLegend what colors and data range to use, e.g. {ColorData["Rainbow"][1 - #1/0.22] &, 10, " 0", "0.22", LegendPosition -> {1.1, -0.4}}.

comment 3D Random Walk with Periodic Boundary Conditions
For a start, (Label[begin]; p[i] = RandomWalk[T + 1]; If[i == n, Goto[end]]; i = i + 1; Goto[begin]; Label[end];); can surely be done more efficiently as a Table command: Table[p[i]=RandomWalk[T+1],{i,n}].

comment How to run a Mathematica program using command line on windows?
@Ajasja - I always count the contribution as how much effort it would have taken me to work out. I'm no Windows export, so those bits would have taken me a while. I got 60 points out of it before I switched it, which is plenty given the kind of answer it is.

@drN I think it's commendable that they are running regressions in high school!

comment Estimate error on slope of linear regression given data with associated uncertainty
Welcome to Mathematica.SE! Can you please confirm that you plan to do this analysis in Mathematica? Otherwise I think it would be better to migrate your question to Cross Validated.
