is Biotech the right one for me..?

Biotech..is it the right one for me..? ya..i'm asking whether i should study biotech anot..ok..i know that i'm so enthusiastic about coming here and study biotech..but now that i'm here...things seems a bit different than expected..
firstly,i was suppose to be here for the scholarship they're giving me(the 40% tuition fee waiver)..until now...nothing have been heard from them..nor anyone contacted me..
secondly..i seem to lose interest in my once favoured science subjects..as u guys know..chemistry was my favourite..and unbelievably..today...in the chemistry laboratory class...i DO NOT even have the desire to listen nor carry out the experiment..i just did it for the sake of my group members asking me to do..(believe me..they call me mr.ong or tai lou and be the group leader)..
last sunday(which is yesterday)..i browse through the internet..and went to tar college web..then i saw the may intake for their college..(something then pops out to my mind..accounting..highly in demand and i can study there with 100% tuition fee waiver)...after talking to my mum for a moment..she encouraged me to try to apply...i did apply for nottingham as well...for engineering..as for the tar college..i put accounting..(same as my gf..she's there as well)
this morning i called the tar college personnel..enquiring them about the intake..and whether i'm still in time for it anot..they ask me to send up to them 1st..then they'l let me know..
as for nottingham..engineering...it's just apply for the sake of trying luck for jpa scholarship for local private university..
what bothers me is that why did i feel that the chemistry class is not what i want...did i just lose my desire to pursue science..? furthermore..the lecturer knows my bro..he came and asked me whether i'm tzong huat's bro..i said i am..the moment he asked me that...i felt so damn guilty for ever thinking of changing course.. am i here just to continue my bro's legacy here..? or subconciously..i just wan to feel what my bro studied here and experience it here..it feels so weird..why am i so enthusiastic before coming here..and now i'm like 'why did i come here?'.. if i am to be accepted by tar college..is accounting what's suitable for me..? i know i do like sorting out things in an orderly matter..and accounting is high in demand..biotech..?many say it ain't so bright..today itself my mum already sent out my application for tarc...and i shall receive response from there in 3-5 days time..i was hoping u guys can drop your comments on this and help me in choosing the correct thing to do..which is leave ucsi and study accounting..or stay here as the no interest for science is only temporarily...
do drop comments if u feel can help me..thank you...and..read on~
