The quick answer is "Yes, some of the OG questions will have the same difficulty level as the questions you will see on test day"
The OG questions range from very easy to very difficult.
The difficulty level of the questions on the actual GMAT will depend on you, since the test is computer adaptive. So, for example, if you correctly answer only a few questions, then the GMAT will throw a lot of easy questions at you. The difficulty level of these questions will be the same as some of the questions in the OG.
If you correctly answer lots questions, then you will receive difficult questions. The difficulty level of these questions will be the same as some of the questions in the OG.
