new sem

new sem started few days ago... 3rd sem alr... time past really fast.
the result isnt out yet... 2 more days to wait.

totally dont know how to choose the subjects, should i take 5 or 6 sub?
there are 3 ways for me to choose.

1st choice: (6 sub)
mon: env(10-1), law(2-5)
tues: free
wed: qty(2-5)
thur: ser(11-1) (this sucks)
fri: free
sat: mpw(10-1), eco(2-5)
sun: free

2nd choice: (5 sub)
mon: free
tues: cmt(2-5)
wed: qty(2-5)
thur: ser(11-1)
fri: free
sat: mpw(10-1), law(2-5)
sun: free

3rd choice: (6 sub)
mon: env(10-1)
tues: cmt(2-5)
wed: qty(2-5)
thur: ser(11-1)
fri: free
sat: mpw(10-1), law(2-5)
sun: free

comparison:
1st choice:
~need to be very rush, since mon ballet on 7, and most probably taking public transport.
~mon class will be having with senior
~4 days, 6 subjects

2nd choice:
~better law lecturer on sat, with part-timers
~have transport everyday
~4 days, 5 subjects

3rd choice:
~law on sat
~mon public transport
~5 days, 6 subjects :(

anyway i choose, i still will be having whole day class on sat. =( then sat ballet terpaksa change to sun, 12.45-2... no more outing on weekends, no more weekends for me
even busier after feb...
