MBA/PGDM

It's good to see your awareness and seriousness towards cracking a management entrance exam so early. Still, in the first year, there is ample time for you. You can start improving your vocabulary by reading good novels/books and newspapers daily(especially the editorial columns). Solving some good logical puzzles and related questions will also help in keeping your mind fit and sharp. Nothing much needed to do for Maths, as of now. just ensure your basic concepts are strong. 1-1.5 hours is quite sufficient to prepare for the time being.
One important thing, there is absolutely no need to start a full-fledged preparation for CAT(or any other entrance exam) now. Focus the next three years on both enjoying your college life and studying well; this phase will never come back in life so make the most of it. Ensure you score well in your exams(it will prove very helpful afterward) and try building your profile by participating in college's extracurricular activities, certification courses or an internship if possible during vacations, social work, etc). Your profile will help you get that edge over others. All the best!

1. Interpersonal skills
Since QS research began, soft skills have always topped employers wishlists. Interpersonal skills are, of course, essential for anyone in a leadership role, in which working with and inspiring others can really make the difference between success and failure be it with clients, peers or those youre managing. And lets not forget, lacking such skills will seriously impede your ability to engage in that all-important networking no ones going to share the hottest new opportunity with you if you cant engage with them.
2. Strategic thinking
Strategic thinking is a cornerstone of the MBA one of the main intended outcomes of the degree has always been to help you move from a functional role to a big picture one. Are you able to see the future of an organization, and how its going to get there, factoring in the agility to deal with competitors and market forces? If so, you will find yourself much in demand with top MBA employers.
3. Entrepreneurial skills
Entrepreneurial skills are the ability to spot a gap in the market, judgment enough to know whether its worth filling and the creativity and technical understanding, if not ability, to do so can be invaluable to a dynamic organization with designs on growth. And remember, not every example of entrepreneurship needs to change the world.
4. Communication skills
Being able to communicate up, down and across is essential in any management position. Communications skills are an area employers have often found candidates somewhat lacking. Luckily this is also a skillset which an MBA will help you to foster, with working in diverse groups with all its concomitant challenges playing a significant role in MBA learning.
5. Leadership Skills
A good manager will possess leadership skills to facilitate the carrying out of functional roles by his or her subordinates not an easy undertaking, by any means. However, a good leader will inspire those who work with them and around them, make them feel valued and give the whole undertaking a sense of direction. Notably, this was the skill surveyed top MBA employers were most satisfied that MBAs possessed.
