There are quite a lot of them, and I just thought downloading them all by hand would be too much work for a Lazy man like me.
Then I used vim to help me :)
I just got the code where there were the links I wanted. It looked more or less like this:
<a href="2006t-c-40-lc-s-test.pdf"> solució del test</a>;
<a href="2006t-c-50-dc-test_resuelto.pdf"> solució del test</a>,
Just open vim, paste the code and let the magic begin.
Now you just have to execute the script, and enjoy :)
Btw, yeah, I know about downThemAll, but I like using my own tools (and I dislike bloat).
