It is completely normal to have an interest in both finance and marketing, as they are both important and widely applicable areas of business. To explore your interest in finance, there are many short, introductory courses available on platforms like Udemy that can be completed at a relatively low cost, such as for no more than INR 500. Additionally, you can read basic finance books from any commerce background to gain a solid foundation in the subject. Similarly, for marketing, there are many courses available on platforms like Udemy, as well as other sites. However, it is worth considering that pursuing an MBA program with a fresh mind and an open outlook for many possibilities may be beneficial for gaining a comprehensive understanding of marketing.

In addition to gaining specialized knowledge in finance and marketing, it is also important to have a good understanding of MS Excel and Powerpoint. These skills are widely used in the business world and will be beneficial for any professional in any vertical or specialization.
