You should only ever sign up for a Beta book if you are sure you can read and submit the questionnaire by the deadline in the sign up information for that book. 

And while we understand that sometimes unexpected circumstances arise that are outside your control, failure to meet the deadline does mean that the job was not completed as agreed and thus you will not be paid for that beta book job (that money will be refunded to the author).

However, if you know you won’t be able to meet a deadline ahead of time, please contact Hidden Gems ASAP to let us know. While you still won’t be paid for that job, depending on the circumstances of the situation and how far in advance of the deadline you let us know, it may help in regards to staying in the program. Especially if this isn’t something that occurs with you often.  If it is, it is an indication that this program may not be for you. 

And even if you can’t get it in on time, you are still encouraged to send it in as soon as you can as that will also go a long way to maintaining your status as an Active Beta Reader.  And incomplete questionnaires prevent you from being sent any further book offers.
