Dear Applicant,

Yes, you can surely apply for iit jam. Since you are doing zbc ie. If its Hons do your last year in chemistry if possible as it will help you alot to clear the exam for MSC. The portion for msc entrance is basically all about the concept of chemistry from sem1 til sem 6 so make sure you are good with the basics. If that's the case you will clear the exam with a good rank.

All the best and do well I wish you good luck. Hope I was helpful towards you
