thanx for answering the question but here's another one
Does TOEFL has these two types of tests and if the answer is negative then will that give Ielts more credit than Toefl
Your welcome
TOEFL has 3 different versions:PBT, CBT and IBT, PBT is easire one
You can take PBT or IBT in iran, just go to sanjesh.org for more information
TOEFL is not like IELTS, it has no Academic Versions, I mean PBT , CBT or IBT are not the matter of difficulty, they are the matter of method of test taking, for example PBT is by paper, but IBT is online test
About your second q
There is no way to compare IELTS with TOEFL, they are used for different purpose and both of them are accredited as well
Usually American Universities asks for TOEFL,
Canadian Universities Asks for IELTS but TOEFL is accepted in many cases
European universities mostly accept only IELTS
Australia Only accept IELTS
For immigration to Australia or Canada, General IELTS is required
You should know what you need your certification for, then you will apply
If there is any more question, don't hesitate to ask
Good luck
