Labs 1b and 2a have been updated today with minor fixes to account for newly discovered typo's, improved screen captures in the instructions and a new icon appearing in Salesforce as part of their recent Spring release.
As always, the updates have been made to the files in place so when you download them now, they will be the new improved version. Here's the link to that same Google Drive folder containing all the lab PDFs for students.
Remember you can always find that same folder by going to MaxProfs > Resources > Essentials too.)
