BSc Biology: Course, Admission 2025, Fees, Syllabus, Exams, Top Colleges, Career Scope

One of the most popular BSc programs after 12th Science is the Bachelor of Science in Biology, a field that is closely related to the life sciences. Over the three to four years that make up the undergraduate program, students are taught a wide range of subjects. A Bachelor of Science degree in Biology emphasizes the study of the unifying principles of Biology, namely Cell Theory, Genetics, Homeostasis, and Energy, from the study of living organisms and their distribution to taxonomy.

With a BSc Biology degree, students will be able to make their career in the field in several areas where a graduate may start working. With the course, students are able to learn about human organisms, environment, and other life forms.

Students can work as Researchers or consultants as per their skills and areas of interest. Excellent packages are available for them if they ensure hard work and attention to detail. Students can go for higher studies in the same field.

 Below are the points regarding who should pursue the BSc Biology course:

• Students who want to pursue a career in Biotechnology, Pharmaceuticals, and Agriculture can enroll in this course.
• Those who have the zeal to learn and contribute to the advancement of research, healthcare, environmental conservation, or education can pursue this course.
• Who want to advance their knowledge in BSc in Biology subjects like Genetics, Ecology, Physiology, and Evolution should study the course.

In order to pursue a BSc Biology course, students must develop certain skills required for a better understanding of
the subject. To give full effort and devote much time to the course, a student's interest is a must. Some of the
essential skills for the BSc Biology are as follows:

• Research Skills
• Laboratory Skills
• Analytical Skills
• Attentive, Investigative Skills
• Communication Skills

Yes, fortunately, many BSc Biology colleges in India offer admissions on the minimum passing marks or entrance exam score basis. However, you must fulfil the basic requirements such as Physics, Chemistry, and Biology in Class 12 from a recognized board.

No, you cannot opt for a BSc Biology course with PCM subjects in Class 12. To be eligible for a BSc Biology course, you must have passed Class 12 in the Science stream with PCB (Physics, Chemistry, and Biology) as core subjects. 

For admission in Universities through CUET (UG) - 2025, the existing policies regarding quota, category, relaxation, reservations, qualification, subject combinations, preferences etc.. of the respective University / Institution shall be applicable. For appearing in CUET exam there is no age limit, however, candidates will be required to follow the age criteria (if any) prescribed the university in which candidate is desirous of taking admission. As the eligibility criteria for admission may be unique for every University, the candidates are advised to visit the University website to which they are applying for their respective programs.

Mere appearance in the CUET exam will not guarantee admission to the programme untill the candidates has:

• Studied subject (s) in major
• Fulfilled the subject combination criteria

CUET UG, or the Common University Entrance Test for Undergraduate programs, is a nationally administered entrance examination facilitated by the NTA. Established in 2022, CUET UG holds prominence as a key entrance test for undergraduate admissions across various participating institutes.

This exam provides aspiring candidates with a unified platform to seek admission into undergraduate programs offered by leading colleges and universities across India. Conducted annually, the CUET exam spans over 500 cities in India and abroad, utilizing a computer-based mode.

The examination is organized in multiple phases, the number of which is contingent on the total registration of candidates for the entrance test.

NTA commenced the CUET registrations 2025 at cuet.nta.nic.in. Candidates can now fill the online CUET application form online on official website. Candidates will be able to enter the personal, educational and CUET subject details to appear for the exam. Candidates must pay the CUET application fee to complete the registration process.

The difficulty level of the CUET exam ranges from moderate to tough. Since the CUET UG exam is held for multiple subjects and slots, the difficulty level of the exam varies from subject to subject.

While for the well prepared candidates, the difficulty level will be low, for the underprepared students, the level of difficulty will be on the higher side. 

Indian Institutes of Science Education and Research (IISERs) conduct an entrance exam in order to provide admission to candidates in the five-year-long BSMS dual degree programme offered by them. The IISER Entrance Exam 2025 format is multiple choice questions (MCQ), where four options will be given to the candidates against a question. Check here:

• Mode of Examination: Computer-based test (CBT)
• Total Questions: 60 Multiple Choice Questions (MCQs)
• Subjects: Biology, Chemistry, Mathematics, Physics (15 questions each)
• Duration: 180 minutes (3 hours)
• Marking Scheme:
  • +4 marks for each correct answer
  • -1 mark for each incorrect answer
  • 0 marks for unanswered questions
• Total Marks: 240
• Syllabus: Based on NCERT syllabus for Classes 11 and 12

The IISER Entrance Exam syllabus is in tune with the Class 11 and 12 Board exam syllabus. The questions in the examination are asked from 4 domains of Science subject, which is Mathematics, Biology Chemistry and Physics.

As per the syllabus mentioned in the information brochure of IISER 2025, it is observed that in Biology subject maximum syllabus is covered from class 12 book. For the subject of Physics. Mathematics and Chemistry the syllabus is equally distributed in class 11 and 12.

B.Sc Biology is a combination of 6-semester put together in 3-year to complete the course as the aspirants focus on living organisms' aspects in the relevant area. Specialization in research-based practical experiments projects until the last semester sharpens the aspirants' skill set and work experience. The course structure is:

• VI Semesters
• Core and Lab Subjects
• Internship
• Projects Submission

The best-related books authored from all over the world in the fields of B.Sc Biology.

Determine every subject on which you must concentrate. Create a comprehensive plan to address such issues. Review the subjects that you find more challenging. Go over the practise exams. Look at the question from last year and note the key points. Try to comprehend the paper's design.

Here is a general summary of the CUET syllabus:
