can I get CS in LNMIIT with 32000 rank in obc category
At this point you should know that there is no reservation in lnmiit so your obc category will give you no advantage although you can get a seat in lnmiit but specifically cse seat may not be possible as in 2020 the cutoff for cse was about 145 marks injee which gives you a rank around 12-15k so according to that you will not get cse stream although you can get streams like ece and other also your jee rank is decent enough to get you some good colleges you can predict your college by this link https://engineering.careers360.com/jee-main-college-predictor?icn=QnA&ici=qna_answer
