Today I have failed on the exam 70-458 because of the time limit.

I have had 85 minutes to complete 51 questions, which is ridiculous.

On my previous exams I have had 120-150 minutes to answer 40-50 questions.

The official Self Placed Learning Kit also states that the time limit is 120 minutes for 45 questions.

Even Pearson Vue gives 120 minutes as a time limit:

What's more, I do not how to get 30 extra minutes for not having English as a mother tongue.

In fact, nobody I have contacted (Pearson, test center, Microsoft) has any idea about how to get this extra time.
