Please get in touch ASAP with the lecturer for the module/s that you have missed sessions from. Failing that, contact another academic member of staff from your course. Try to do this as soon as you can so that they are aware of the reasons for your absence.
Assuming you re-engage with your studies there should not be an issue. Should you continue to be absent or do not make your circumstances aware to your course you could risk being withdrawn from your studies. You will be notified of your withdrawal after three previous written attendance warnings.
If there are personal reasons for your non-attendance and you would like to discuss these and receive advice or guidance then please log an enquiry through Compass Online.
