The best courses in BSc are in the following fields:

• B.Sc. Agriculture
• B.Sc. Nursing
• B.Sc. Horticulture
• B.Sc. Zoology
• B.Sc. (Hons.) Computer Science
• B.Sc. (Hons.) Physics
• B.Sc. Biotechnology
• B.Sc. (Hons.) Chemistry
• B.Sc. Biochemistry
• B.Sc. (Hons.) Mathematics

I am a bit confused regarding your second part of the question. Can you please specify what you mean by 'your'? There are various colleges which provide many of these courses with their own entrance examinations and criteria. So, kindly elaborate on that part! Other than that, hope this helps!
