* Bachelor's Degree (BSc): This typically takes 3-4 years of full-time study.
* Master's Degree (MSc): This usually takes 1-2 years of full-time study, sometimes longer depending on the specific program and research requirements.
* PhD: A doctoral degree in zoology is a research-focused program that generally takes 3-7 years or even longer to complete.
Therefore, there's no single answer. You need to specify the degree level (Bachelor's, Master's, PhD) and check the specific university's program details for accurate information.
