Difference in Schweser Qbank on-line & CD

What are the differences in terms of; 1. Number of questions 2. Simillarity with real examination questions 3. Level of difficulty

I believe it is the same, with the only difference being how you access the questions. On-line you can access anywhere with internet access, CD can only be installed on two computers.

I bought the online version since I use a Mac at home. It’s convenient as I’ll be able to access it from work. Why bother with a CD that you can only install on 2 machines? From what I can tell, the question bank is still the same.

Apart from LOS related questions, does it contain quantitative/qualitative questions simillar to Exam.
