Does number of attempts in elitmus affect our chances of getting calls?
Yes, it may lower your chances. But not that much.
Exam like eLitmus is tough and not every candidate clears it in their first attempt.
I know someone who took 5 attempts and still got a job.
Most people say that you should keep your attempts lower that 3.
Don’t worry.
Prepare well.
All the best.
