Hii!
Both the courses, that is, BSC technology and BSC zoology have their own scopes and opportunities. You need to decide which one would you prefer as per your interests.
From BSC technology, you can get into fields such as  electronics, manufacturing, business, finance, banking, police, railway, defence, information technology, automobile, communication, education,  entertainment etc.,
From BSC zoology, you still can join some of the above mentioned options such as education, communication, railway, entertainment, business etc., Along with other options such as zoology faculty, wildlife educator, conservationist, wildlife biologist, forensic expert, lab technician, veterinarian, animal behaviourist, zoo curator, etc.,

Hope this helps.
Good luck!
