Yes, you can. But do check your age eligibility. All the best !!

See, ranking depends on both, your 12th % and JEE score. So, if you want to be in 3000 rank, your board marks must be around 95% and JEE score must be 220-230. Its all approx, bcz ranking depends on the performance of other students too.

AIR will be declared on 30th of June or a little before.

No. Don't wait any more. You'll be wasting another year. Just move onn. Do something else like BSc or BCom.

JEE Mains cutoffs are the minimum marks scored in JEE Mains out of the total of 360marks. For example, this year cutoff for General category was 100 marks. That means, if you are a General category student, you need to score atleast 100 marks out of 360 to qualify to sit in JEE Advance.

Which category you belong to? If you're ST then easily you'll a NIT. If you're SC, then also you have a good chance. Try the NIT in your state, you'll the state quota. Goodluck !!
