Science

Hello there,
Both, Biotechnology and IT, are boon to India and world and to employment as well. However, both sectors differ from each other in many ways. But, they are also related in some space. Since BCA is totally concerned about computer applications, and there is a lot technology involved in biotech (for example - instruments and softwares), you can share a hand by developing applications that could be use in Biotechnology.
But if you have interest in research area, please go for B.Sc in Biotechnology.
Focussing on the job after these courses, both BCA and B.Sc Biotechnology graduates need to have proper understanding of the field. However, jobs are mostly possible after PG only.
I hope my answer help you in any way.

Any student who is contemplating on pursuing a career in Biotechnology must be aware that this field is still developing in India. Therefore, the number of job openings and pay packages are both very low when compared with IT and CS fields.
After a B.Tech degree, students can find jobs in pharmaceutical companies, research labs and institutions in India. However, most Indian students tend to go abroad to pursue their Masters or doctorate studies in Biotechnology and allied fields. Some students also shift to MBA and enter the world of business, finance and banking as their engineering background gives them the required quantitative skills to excel in these sectors. Also, many students shift to software through on-campus placements. Talking about on-campus placements, since the number of job openings is very less in Biotechnology, the number of companies coming for placements will be very less. Also, core companies only hire students from universities such as IITs, NITs etc. If your university is not reputed nationally or state wise, chances of any biotech or pharmaceutical company coming for placements sessions will be close to nil.
Since this field is highly research oriented, vast and diverse, it is highly recommended that students pursue their graduate studies in Biotechnology, Biomedical sciences, Biological sciences, Bioprocess Engineering, etc.

I would like to share a few tips that can surely push your moral as well as confidence to score maximum out off which you are desiring to score-
1. Study regularly, take out time for at least three subjects in a day. Work more on those subjects, in which you feel you are weaker than other subjects.
2. Do not leave any subject for more than 2-3 days. Every subject should be taken up for study at least in every alternate day.
3. Devote at least 6-7 hours for self study. Take out a bit of time for relaxing and entertaining also.
4. Whenever you study, don't sit for too long continuously. Take one or two short breaks of 5-10 minutes.
5. Be in touch with the previous years papers, sample papers etc.
6. Whenever you give a test in school and obtain marks, just go through your answer sheet seriously and see where marks have been deducted and how can the errors be avoided next time.
7. Take proper care of your health and hygiene. Do regular exercise, take more of green vegetables, milk and other nutritious food. Do not get tensed.
8. Although you must stick to NCERT books, but in Science, maths, you must do some extra questions also. You can purchase a good book or question bank for that.
9. Be in contact with your teachers and ask them to evaluate yourself.
10. At the end of the year, do at least 8-10 model test papers for each
subject. This will help a lot.
Just keep working towards your Goal and keep on evaluating yourself.
Also a few suggestions to increase your concentration-
-Start assignments with some curiosity about the material and a positive attitude toward learning.
-Identify your distractions. Find ways to decrease them or to postpone them until study breaks (e.g., taking the phone off the hook, turning off instant messenger).
-Decrease noises around you while studying. If you need some background music it should be soft. Keep the TV off.
-Use "active study" techniques: sit straight in a chair at a desk, start out with questions about the material, outline chapters, underline key phrases after reading a section, write notes in margins, ask yourself what you have learned.
-When your mind starts to wander come up with some cue words to say to yourself (e.g., "Focus." "Get back on task.") to focus your concentration again.
