Dear Candidate ,
Yes , you can apply to IET Lucknow for B. Tech with your 87 % in Class 12 and CUET UG score even if you have not given JEE mains . While JEE main scores are usually preferred , IET also considers CUET UG scores for admission through UPTAC counselling , especially if seats remain after JEE candidates are admitted . Make sure you meet the eligibility criteria, have all necessary documents ready , and participate in the counselling process . Keep an eye on official dates for application and counseling, typically starting around May - June .
