There is a misconception that PTE is dead easier than IELTS. Although it remained easier till the end of 2014, from 2015 onwards ,getting scores of 65 in all modules hasn’t been as easy as many might think.The current scenario is that,for scores upto 65 in all modules ,PTE would usually be easier than IELTS
if you been educated in English medium at least from the 11th standard( Intermediate /10+2) onwards
if you been communicating in English for the last 5 years in your profession,
if you have at least neutral accent ( accent free from MTI) if not native accent,
if you have had quit some reading habit.
On the other hand, for scores upto 65 in all modules, PTE would mostly be tougher than IELTS,
if you have been educated in non-english medium even after the 10th standard, nor have you been using much English in your work life,
if you carry a stong mother tongue influence (MTI) on your accent,
if you haven’t had much reading habit,
if you have difficulty typing.
For scores of 79 in all modules( 8 in all in IELTS ),PTE would indeed prove tougher than IELTS ,no matter what your profile ,ability and exposure are !
