Zoology

Yes with your B.Sc. in Zoology and M.Sc. in Animal Behaviour you are eligible to appear for the UGC NET exam. The UGC NET exam is conducted by the National Testing Agency (NTA) on behalf of the University Grants Commission (UGC) for determining the eligibility of candidates for the role of Assistant Professor or for the award of Junior Research Fellowship in Indian universities and colleges. 

To be eligible for the UGC NET exam you should have completed a master's degree (or its equivalent) with at least 55% marks (50% for reserved categories) in the relevant subject. As you have an M.Sc. in Animal Behaviour you fulfill this criterion.

In addition to the educational qualification there are other eligibility criteria such as age limit and nationality that you need to fulfill. You can check the official notification or website of UGC NET for more details regarding the eligibility criteria and application process.

You got RT in chemistry. So, you have to appear for compartment exam to clear that subject after that you can apply for ICAR entrance exam.

In eligibility criteria of ICAR, it is written that candidates must have completed 10+2 coursework in Physics, Chemistry, Biology, Mathematics, Agriculture, and/or Home Science.

Same for B.Sc zoology honours also.

At least 55% of the total marks on the Senior Secondary School Certificate or an equivalent test must be earned in English, Physics, Chemistry, and Biology/Mathematics.

Note: Candidates must have passed Biology on the qualifying test in order to be admitted to the B.Sc. (Hons.) programme with botany or zoology as the main subject.

No, you cannot do a B.Sc in zoology to correct your subjects' combination for TGT teacher after having completed a B.Sc in biotechnology.

The eligibility criteria for TGT teacher in most states requires the candidate to have a B.Sc degree with zoology and botany as the main subjects. Since you have already completed a B.Sc in biotechnology, you will not be eligible to apply for TGT teacher posts.

However, you can still pursue a career in teaching by doing a B.Ed or M.Ed degree. These degrees will not require you to have a specific subject combination, so you will be eligible to apply for teaching jobs in any subject.

Here are some other options you can consider:

• Do a B.Ed or M.Ed degree. These degrees will not require you to have a specific subject combination, so you will be eligible to apply for teaching jobs in any subject.
• Do a PG Diploma in education. This Diploma will give you the skills and knowledge you need to teach in a school.
• Get a job as a teaching assistant. This will give you the opportunity to gain experience in teaching and to see if it is a good fit for you.
• Start your own tutoring business. This is a great way to use your teaching skills and to help students learn.

I hope this helps!
