The age limit depends on the university and the country in which the Bachelor of Science program is enrolled. Most institutions do not enforce an age bar limit, and a student is free to join college at any age. However, some institutions have a minimum age limit, usually 17 or 18, to allow only those who have completed their pre-university education and all other essential requirements.
For students coming back to studies after a considerable age gap, many universities offer flexibility to learn, like part-time or distance learning. Professional fields such as medicine or aviation have strict age restrictions because of their eligibility norms. A standard B.Sc. in physics, chemistry, or mathematics is opened for all applicants who are eligible to join the course, but if one contemplates admission in a B.Sc. It is good to check for any age policies in the respective university if applicable. Most colleges embrace lifelong learning and accept all ages.
