Hi,

I'm not good at "How many times will a certain digit written" types of question. Although I don't know how to say this type of question expactly, here's a example of this type of question in the GMAT Club test.

**Quote:**

How many times will the digit 7 be written when listing the integers from 1 to 1000?

digit-81744.htmlI can understand the explanation of the question, but I'm not sure whether I can solve similar questions with confidence.

Do you have any good resources or books to provice a conprehensive and easy-to-apply approach to solve this type of question? Or, do you have question bank filled with this type of question?

I have about 3 weeks to take the first GMAT. I took MGMAT's first CAT test and got 620 (Q36, V38). I believe improving my Q score will boost my score. That's why I should get over my weak points mentioned above.

Thanks
