look. if you do bsc then brace yourself as you will have a long road ahead. years and years of study. and of difficulty that you haven't imagined before. now, if you take btech. you will end your education within 4 years.
@tryhard what if u do bsc from a normal University and then msc in chem from a good University???....will it change the outcome??
or will it be Same??
look it will still take a lot of time. like obviously your study in bsc doesn't end with msc. you need to doo PhD and research as well. or go to teaching line. now it's about you. do you want teaching line or PhD. if you want to do something extraordinary then you'll have to study more and do PhD and then further research. if you want to go to teaching line you need to make sure that you have a passion for teaching otherwise it's a really tough profession that can make your life hell. but do not be scared. all most any occupation without passion ends up being painful. just decide properly what are you passionate about and then go with it. it can even be outside BSC or eng. whatever you find interesting. because I can assure you that by doing that you will save thousands of rupees from alcohol and therapy if you make the right choice and choose what you are actually passionate about.
if you're thinking about Chem, in future you can study drug chemistry or organic chemistry which can be helpful and an industry based approach. teaching is another way to go. as for engineering, do a little research for the branch you're interested in and what jobs you can apply for later. then compare the pros and cons to consider your field.
