Hello aspirant!
Well the marks scored in EAMCET will be given as 75% weightage and marks scored in Intermediate Public Examination will be given 25% weightage.Rank is calculated by combining the percentages of scores obtained in each section.IPE marks are considered in preparing the final rank of EAMCET Exam.Having a good percentage in Intermediate will surely account to high score and good rank in EAMCET provided you have a decent score in EAMCET.

Hope it helped!
All the best!
