The instrument is still not working, so the group doing the second week of A2 (Lee, Ben, Ravneet & Seth) is not required to attend the morning class. Your first attendance should either be the 12-1 tutorial or Instrument Maintenance at 1.30. Results for A2 to allow you to write up the report will be provided tomorrow.
The group doing the first week of A2 (Karolina, Ash, Tim, Tanya & Tianna) is still required to attend, to carry out the calculations and planning. It is not essential that you arrive at 9 sharp for this.
