I strongly suggest you to change the subject to some technical field. BIOLOGY/CHEMISTRY is the worst choice unless you're planning to go to Medical college or do Pharmacy.....Let these people say whatever they want to, they probably have realized by now Bio/Chem is waste of time and money. Even if you do PHD, you're not making good money in this field.
Do u enjoy working in labs all day doing some crap research ? if yes go for Bio.
Do u enjoy pippetting all day in lab ? that's what the job you'll get it.


Go change it to IT or computer science or Pharmacy or Physical therapy, Occupation therapy, Epidemiology, Biostatistics....

Good Luck .
