Hello Shashank,

18109 is considered as a good rank the cut offs aren't out yet that is the opening and closing rank for different branches as it may depend upon many factors like number of applicants fill the form, number of applicants finally appeared in the exam, number of questions asked in the exam, difficulty level of the exam, performance of the candidate, previous year's cut offs trends, availability of seats in the instituion that is the reason that every year's cut off is completely different from the previous one. According to the VITEEE college predictor with this rank you may get a seat in ECE and mechanical in Chennai campus but in the end it only depends upon this year's opening and closing rank you this prediction could be wrong if you want you yourself can go thorugh the rank predictor I am previding you the link for it
