What is better to pursue among physiotherapy and a B.Sc. (biotechnology)? This is an open-ended question. It depends on your passion, interest, foundational qualifications, and what you love doing.
1. You need to know what both courses entail.
2. You should know the ultimate outcome of studying either of them and determine if they are in line with your desired future. For Physiotherapy, you will be in a profession that is dynamic, fulfilling, financially rewarding and intellectually demanding. This is similar for biotechnology. Biotechnology involves a lot of laboratory work and long-term tinkering with genes, molecular structures etc. Physiotherapy involves the treatment of health conditions using physical means majorly exercise etc. I feel this may help.
