Holidays

 Now, semester 1 in my foundation of engineering at Swinburne Uni is over.. Currently I'm enjoying my holidays before my next Summer Semester (2 months) just for MPW.. Screw you MPW..you're totally ruining my holidays..
Honestly speaking, now though I'm enjoying my hols, but i'm worried about my exam.. I know i did very poorly for my physics and e-maths a.. I need to get at least 50% in order for me to progress to next sem. My coursework for these 2 sub is only 25%..that means i need to score at least half for me to pass..
Now I'm really worried..can anyone help me,please?
