Hi,

Difficult and Easy are relative and subjective terms when it comes to studies. What makes a subject tough or easy is your interest / inclination towards that particular subject.

Zoology deals with studying animal life and botany is all about plant kingdom , what matters here is your interest level or curiousity to learn.

It's depends on you which subject you like most and can understand easily. You can not say which one is easy or not both are the branch of same that is biology.

Msc in any Biology brach involves : theory and practical. While dealing with theory, Zoology is way more easier to understand and reciprocate during exams as compared to Botany. On the other hand, practicals in Botany is easier than Zoology.

In terms of scope and salary both are at the same level , the highest salary in both areas would be around 8-10 LPA.

So choose wisely so that you don't have any regrets.

Regards.
