First year looking to transfer course next year, WAM vs ATAR

Hi guys,

I'm a first year looking to make a transfer in course (into Law) next year. I received an ATAR a bit below the cut off for last year (99.30, and cut off was 99.50 strict I believe). From what I've gathered, if you've done more than 48 credit points worth of study, they take your WAM into consideration, and if not, they just take your ATAR/other secondary qualifications.

I was wondering a few things:

1. If WAM wasn't considered, would a 99.30 be a very competitive secondary qualification (for transfers) to get into Law?

2. If so, could you intentionally 'underload' units so that you end the year with say 42 credits, and so WAM wouldn't be considered?

3. If that wasn't possible/a good idea, with a 99.30 as a part of the secondary qualifications, what would be a competitive WAM I would need to achieve?

Thank you guys all for your time!

Oh and also, where/what bodies at uni could I consult about these things?
