I have completed 12 with physics chemistry math and biology. what will be my course duration for chemical engineering in a polytechnic college
The duration depends on the curriculum set by the college by generally a Diploma in Chemical Engineering is course of 3 years.And i strongly recommend you to not purse diploma course after 12th.You should have done after 10th and if you will will do a 3 year diploma now then it will be a waste of 2 years of your 11th and 12th.
So, either do any simple graduation course or any go for B.tech in Chemical engineering.
I hope this helps.
