Woo... CAP of 3.7, that is exactly the same as mine when I was
in year 1 sem 1..
Anyway, what course are you in? This is because different course
allows you to S/U different type of modules. Also, are you from
poly or JC? This is because poly students are exempted from some
modules, meaning to say they have lesser electives and UE modules,
therefore lesser modules to S/U, whereas for JC students, they need
to do more modules than their poly counterparts and therefore they
have more chances of getting bad grades and thus needing to S/U
them.
Anyway, dont be disheartened on your CAP of 3.7. I did badly for
my first year as well, getting 3.7 in my first sem and then further
dropping to 3.61 in sem 2. But then I worked hard and I got a CAP
of 4++ now.
From my experience, I can only say that, first, you need to work
hard and get at least A- and B+ to push your cap ab above 4. First
year is the year in which you will see your CAP fluctuate alot, and
second year moderate fluctuation, third year, some fluctuation and
last year, minor differences (0.01 to 0.1 kind).
Try getting some A and A+ in your next semester and to pull your
CAP higher. Do not get any B or B-. If you get a B-, you must at
least get an A to counteract it, and thus giving you a B+ for both
modules. Its best to have a higher CAP score in the first 2 years,
and this will give you extra motivation to maintain it.
However, you must also be prepared that even though I say that
your CAP fluctuates less in year 3 or 4, getting a C+ or C-, would
not doubt still pull your CAP down. I remembered that during my
year 3, I used an A and A- to balance off my B and C+, and I can
tell you, it was damn painful getting a C+.
Anyway, to answer your question, yes you should S/U your B-. A
CAP of 3.875 is a good starting point. Try working harder and not
to get anymore B- or C. As long as you maintain a grade of B+, then
you probably would not need to S/U anymore in the future as the
difference between before and after S/U-ing is not going to be
much.
So, just S/U this module and work hard. Save your other 2 S/U
options for the future in which you get a grade that is so fucking
lousy that it pulls your CAP down an honours level, otherwise you
probably wouldnt need to use them anymore if you study harder.
