I think got chance, you need to do something to get an "A" for
your industry attachment.
First you need to look at:

If your credit is 8, and you score "A", you get a grade scale of
4, which leads to Grade point of 8 x 4 = 32.
Semester GPA will be Credit Earned/Credit, which will be 32/8 which
will be 4. Cos you only have one module this semester
The above will be your semester GPA
Your worry(and every students') will be calculating your
cumulative GPA.
If im not wrong, Cumulative GPA is calculated by: (Summation of
total grade points of your ITE years)/(summation of the total
credits)
Since 3.3 to 3.5 is a 0.2 increase, i think there is a high chance
of possibility.
Even if u maintain at 3.3, you can still appeal into
polytechnics, got money sure can study in singapore.
