I think you will find your real lessons very different to the ones that come with Flight Simulator. FS teaches you to fly by using the AH. It'll prepare you well for IFR but that's not how you will be taught to fly VFR. The flights in the book "Flight Simulator for Pilots" are much better , although geared for the FAA license.
The time to is Flight Sim is AFTER you have been taught by an instructor. Go over what was in your lesson and do it the way your instructor told you - not the FS way. If you are training in a Cessna 152 then get the add on for that.
As a PPL I quite often used FS. It's very helpful for learning to fly IR (I haven't got there yet). Arguably it helps with practising landings although the texture resolution is nowhere good enough those last few feet. It can also be frustrating as flying FS is often more difficult that flying for real.
