Frankly speaking, I’ve never come across this esldrill until you posted the first exercise in a Whatsapp Group. I went through it. Literally it is a wonderful experience doing the exercises. Every question is quite interesting and most challenging. This is very useful to the students, especially to those who dream of achieving 10 GPA.
Besides comprehension part, the questions regarding vocabulary and grammar are awesome. I strongly feel this esl drill will create competitive spirit in the young minds. As a teacher I feel these quizzes are quite handier in driving the point home.
