its normal. Many students have trouble planning , and of course we are here to help you out. Since you stated you like chemical engineering , let us know which state you are from so that we can provide you with more accurate information.
Now then, you say you're interested on chemical engineering? Or is it just Chemistry?
If it is just chemistry, then you can go for B.Sc and then M. Sc. From any of the renowned universities of the country, like DU, St. Xaviers, etc.
Otherwise, if you are interested in becoming an engineer, then you better get admission into a better college like IIT or NIT. There are other great options as well, which you can find out in several articles and Questions here on C360.
