With some extra study, you should be able to reach the overall percentage requirements of 55%, so keep your hopes up.

You should definitely go for further studies after the B.Sc. In India, the job scope for Bachelor's degree course is getting thin by the day. Companies are now demanding post-graduate students. The only exception here is engineering students. After B.Sc in non medical, you are presented with some good options. Here are few options I would recommend to you.
MBA
Masters in Business Administration is the first option in front of you. It is a 2 year long postgraduate course after which you will be able to apply for jobs in management, accounting, finance and marketing related fields. To get admission in an MBA college, you would have to appear for one of the entrance exams.
CAT-Common Admission Test is a widely known entrance exam for the MBA aspirants. The CAT score is accepted in some of the best institutes in India like the IIMs, which are regarded as top B-Schools in India. The eligibility for CAT is that you need to score at least 50 percent marks in the B.Sc course. If you belong to SC/ST then you need at least 45 percent marks.
MAT-Management Aptitude Test (MAT) is another great option for the MBA aspirants. Unlike the CAT, Management Aptitude Test does not have any percentage requirement making it more attractive to students with low percentages. MAT takes place 4 times a year in India.
B.Tech
Engineering is another great course you after completing the B.Sc course. These days AICTE allows B.Sc students a lateral entry in the engineering college. What lateral entry means is that you will get admission in the second year of the engineering course, whichever you may choose. Most institutes in India reserve some seats for the lateral entry candidates. It ranges from 5 percent to 10 percent.
Eligibility:
You must complete your B.Sc from a recognised university in India.
B.Sc non medical candidates are required to score at least 60 percent marks in B.Sc.
SC/ST candidates requires 55 percent marks.
Your age should not be more than 28 years.
M.Sc
Another good option for you is M.Sc course. Once you complete your postgraduate course, apply for entrance exams like NET and SET. If you scored well in these exams, you will get lecturer job in reputed college in India. If you are interested in teaching field then I must suggest you to do M.Sc course.

Good geneticists have a passion & curiosity related to the genetical basis of health and disease. If you want to be successful at this job, you must have patience, good communication skills & perseverance. Those students in interested to make their career in genetics should take science and mathematics as possible in the high school and college.
There are a lot of career opportunities in the field of biology, biomedical and Life Sciences. The job opportunity for a genetics degree holder is continuing to expand. The genetic employees are not sufficient now that's why the demand of genetics continues to increase. Geneticists can work in various capacities for many different types of employers.

Engineering: (except Biology)
As you should have studied other subjects except for medical oriented Biology, Botany and Zoology, you can pursue the engineering degree in other streams. However, to study an engineering discipline at the college level, three subjects Maths, Physics and Chemistry are mandatory to be studied until class 12th. Of all the three, maths is the most important subject to study engineering. No colleges in India accept students who have not studied maths, though chemistry and physics might be an excuse at times. If you qualify maths then you can study BE/ B.Tech in electrical and electronics, Mechanical, Civil engineering, Architecture, Chemical engineering, Mechatronics, Environmental engineering, Automobile engineering, Aeronautical engineering, Aerospace engineering, Production engineering and manufacturing engineering.
If you haven't studied maths until 12th level, then you are eligible to pursue B.Sc Electronics, Electrical and Environmental Science.
Computer science:
If you have studied Maths and Computer science until 12th level, then you are qualified to study an engineering discipline in computer science. Accordingly, you can study BE/B.Tech Computer science and Information technology courses.
If you haven't studied maths at HSC level, then you are eligible to pursue B.Sc Computer science, Bachelor of Computer Applications (BCA), and B.Sc Information Technology.
Commerce and Economics:
If you have studied commerce and Economics in HSC then you may be eligible to study the following courses. BA Economics, B.Com (Bachelor of Commerce), BBA (Bachelor of Business Administration) and BBM (Bachelor of Business Management).
Students who opted for commerce may also wish to specialise in accounts, finance, business, and banking. Accordingly, you can also choose your professional route as an auditor if you study chartered accountancy, Financial planner or analyst if you study CFA (Chartered Financial Analyst) and MBA for business administration.
