You can the GMAT Club tests
(they do allow you to target questions by difficulty).... other than that, you can also take the Kaplan
Quiz - here is more about it: review-of-kaplan-quiz-banks-1001-questions-97150.html
You can take questions by difficulty there.
Much thanks for your quick reply....
I know that GC tests come with the option to select difficulty level while practicing
but thought of using it at the final stage or mid stage of prep you may say...or once I reach 40+ on CAT...
As far as KapQuiz is concerned, I didn't consider it as it doesn't come free like Veritas
quiz bank and honestly, I wanted to utilize another free quiz for practice like Veritas
with only difference in selecting the difficulty level as per my progress...
