DAILY ECA TEST

Hello all EJ/EX students!

I hope everyone's working hard and putting their extra efforts to pass with good marks in the coming summer exams. Keep running, never stop chasing your dreams until you make them a reality...:)

I will be posting a test every day on this blog daily.

I want you all to go through the questions and answer them yourself.

So first go through all the questions, see if you know the answers to all of them.

If not, then first prepare it thoroughly and then sit down and answer all the questions in the specified time.

Follow this pattern daily and you will succeed for sure.

Good luck.:)
