What's 'middle-band'?
If you don't meet the ATAR (e.g. get just under the required ATAR), there's a few criteria that they use to rank those students and determine who gets in and doesn't. These criteria are the ones listed in the VTAC CourseSearch - often it's things like doing certain subjects, getting a score over 30 in English (rather than 25 if that's the prerequisite etc.).
I don't know which universities consider time-taken to complete VCE though.
e.g. for Monash Science:
http://www.vtac.edu.au/cgi-bin/coursesrch/course.cgi?&coursecode=28451"Middle-band: A study score of at least 25 in two of biology, chemistry, geography, mathematical methods (CAS), physics, psychology or specialist mathematics = an aggregate 2 points higher per study, maximum 6 points; SEAS."

Additional factors considered for selection.
• Middle-band factors are considered for approximately 20% of places, after the ‘clearly-in’ applicants have been established based on their ATAR alone.
For more information about middle-band see About selection criteria (page 16).
anyway, if it does turn out that you're able to drop English Language and go off your previous English scores, be sure to consider if you'll still be able to get the required ATAR to get into the course you want with that English score in your top 4. (would there be any other things to think of? I can't think of any other issues)
