I agree with thanos1983 that it looks like you're searching for some kind of nested data structure. Maybe you can try something and ask us how to improve it, or show us how you might expect the data to look like (but it would help if you understood how nested structures work for that). Anyway, there is a nice idiom to access elements in an array when each position has a special meaning, constant:

use strict;
use warnings;
use feature qw(say);

use constant {
  STUDENT     => 0,
  FIRST_QUIZ  => 1,
  LAST_QUIZ   => 3,
  FIRST_EXAM  => 4,
  LAST_EXAM   => 5,
  FINAL => 6,
};

while (<DATA>)
{
  my @fields = split /,/, $_;
  say "Student:", $fields[STUDENT];
  say "Quizzes:", join ", ", @fields[FIRST_QUIZ..LAST_QUIZ];
  say "Exams:", join ", ", @fields[FIRST_EXAM..LAST_EXAM];
  say "Final:", $fields[FINAL];
  say "-----"
}

Here I have used Slices (@ meaning several elements at a time, and a list inside the [ ] rather than a single value, but you can define FIRST_QUIZ, SECOND_QUIZ and so on and access each element one by one if it's simpler to you.

Also in /\w*\s\w*/, the * means 0 or more. So that's "maybe a letter/digit or more, a space, maybe a letter/digit or more", in the end the condition is pretty much only "a space". This might work, but this doesn't look like much of a constraint. Maybe you want + instead of * ?
