I want to know what are the extra subject with BSc Geography (hons) but I don't have science as a stream in 10+2. Can anyone help?
If you wish to go for the BSc Geography Hons course, then in most of the colleges, they state the eligibility criteria to have Geography along with Mathematics in 10+2. So if you don't have the subject of Mathematics in 10+2 along with Geography, you won't be able to pursue BSc Geography, in most of the colleges.
Although, you can do the BA in Geography course. Apart from this, if you wish to take Generic Elective with your BSc Geography (if you get a chance in any college), then it would be dependent on the college you take admission in, which additional subjects be offered. In general, as the BSc Geography course is offered to the student with science background in there 10+2, the electives include subjects such as Physics, Chemistry, Mathematics (Mathematics is a good choice for BA Geography as well), Economics etc.
