First download a demonstration copy of the ithink software.
This is a “save-disabled” version which means you won’t be able to save your models. If you wish to do this and move on to developed more advanced modelling skills, you will need to purchase a full version of the software and you can contact me to get a (free) extended version of the user manual.
Second download my introductory user manual. This has been developed over 20 years of teaching modelling at Monash University and is now relatively idiot proof. The only thing you need to be certain to do is to follow the instructions carefully. If you have any problems, send me a message at firstname.lastname@example.org and I will get back to you.
If you would like to practice your modelling skills download Uncle Ebenezer’s Pine Plantation
