Why some universities tend to investigate the English language proficiency of PhD candidates by TOEFL score and other universities be inclined to IELTS score to examine the mentioned feature?
How is the relation between the scores of TOEFL , IELTS and PTE? For example: Is the score of 100 in TOEFL IBT exam, equal to 7 or 7.5 in IELTS exam?
I was wondering if you share your experiences in TOEFL or IELTS exam...
May you introduce some convenient references to self-study of TOEFL , IELTS & PTE please?
Many thanks.
