sorry sarah, no offence intended in the last post... well not so much for 1a i suppose, but for 1b, most definitely do it with the main stream of pplz...
1b requires much much more team work than 1a, so doesn't really matter.... the main down side would be that in tute u get crummy classmates...
scaling won't go against u, just that u will be alot less fun...
however there would also be pplz like urself who didn't do 1a in first sem but doing it in 2nd sem... so probably won't be that bad...
but definitely do acct tho... tho boring, it's one of the most useful subject i have ever done so far.. (econ's fun, but less practical =p no offence to eco lovers ^^)
