Advice For cramming - Just finished Cisco Academy CCNA Security

Just finished Cisco Academy CCNA Security, yet the depth of my retention of the material feels shallow. I completed all the labs except for the ones requiring ASDM, because packet tracer does not have ASDM. PLEASE give me some advice about what resources to use to prepare for the test.

Personally I felt that PacketTracer didn't really cut it when I took the CCNA Security. And that's probably more the case now that the exam has been updated with new material. So if you don't have access to real gear, I'd look at GNS3 or VIRL. Even if you don't need it now, you will for the next cert you work on.
Edit: Wow, I didn't notice this thread was so old. I guess I haven't been around in a while.
