@Krisdi based on what Ive read from other members ACS will make a recommendation to have the points test advice since they can't assess your non-IT degree. This is a separate fee and you can check this at the VETASSESS website. Yes the deductible years is the 6years I pointed out, but take note it should be assessed as related to your nominated occupation by ACS.
