Netty -
No need to fret about not finding time in a Classic sim. I did mine in the old beast too (although I came off the B737-200 so it was like being at home with everything doubled!). jumpingdoc had good comments. Study and know the sheet well. They'll also brief you on some EPR and Vspeeds during the pre-brief.
Regardless of what equipment you're flying now, practice on your flights if you can. Do "raw" approaches. Don't rely on the automatics. Get your scan back up to par if it's not already.
As for checklists and procedures, apply the ones you are using at your current airline(?). At least call for the basic checks like a "Before takeoff check, after-takeoff check, descent check, and landing check." (These by the way are the ones we use at Cathay).
Don't settle for mediocrity. Like jumpingdoc said...if you're off on altitude/airspeed correct it immediately. Don't be happy with +/- 5 knots or +/- 100 feet....if you can! Try to nail it! Or at least show you're correcting so they know you've seen it and are doin' somethin' about it.
Relax and have fun! Hope yours won't be as exciting as mine...the building fire alarm went off in the middle of my session and we all had to evacuate. Had to re-do the session all over!
Aloha!
