VITEEE Cutoff

Good Luck!

16000 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 might not able to get CSE in chennai branch as there cut offs are usually very high but I think you can get CSE in AP but in the end it only depends upon this year's opening and closing rank but this prediction could be wrong if you want you yourself can go thorugh the rank predictor I am previding you the link for it
