Workflow of the practical course
The practical course begins and ends at the given times! Auxiliary dates only in exceptional cases! (e.g. due to
illness certificate necessary! ) The purpose,the aim, and the basics will be discussed at
the start of the experiment. Sufficient knowledge is a requirement for the participation in the lab course!
Repeated unprepared appearance to the lab course may lead to exclusion from the lab course!

Workflow of the practical course
• Prepare the measuring report in advance at home
• Never start with an experiment, before you received the introduction to the experiment
• The measuring report is attested (Vortestat), if the experiment is finished and your place is cleaned up. – This is not a guarantee that your data are correct! – You are responsible for your measurements!

Protocols• Observe the deadlines for the protocols: One
week after the practical course started, until 16:00 o'clock.
• Evaluation: 0 to 3 Points in steps of 0,5 P. One week after delivery you can look into the evaluated protocols.
• You can look at your protocols during one of the practical classes (Mon at 8:15 , or Tue at 11:45, or Wed at 11:45)
• Laboratory course is completed when four protocols are attested.
