Dear Shreya ,

According to employment Ares now days every employer wants to recruiters candidates he/she can handle everything  so we have to prepper accordingly .We also know only geography will not helpful to grow your carry because now days advance techniques are introduced with we should know the computer application but dont be confuse between choose your subjects .

As per my opinion you should go through (geography + math ) because this things you will not get not much more idea from online and outsides because it is very deep course but you can get computer application subject from various online courses lots of sites .So if you will get free time during your colleges you can enrolment some of basic computer application subjects where you will got the ides of this course .So it will easy for you and you can balance yourself .

Hope it will helpful

Thanks
