Hi Nishant,
It will be reviewed. Please understand that mentors are folks like me and you and hold others accountable commitments like a job, university or school. There can also be timezone differences between you and the mentor and it may be possible that the entire 10 hours may be off working hours for them.
Also, remember the fact that organizations will grade you by the quality of your work and not by the number of tasks you submit. One good task will award you more than 10 poorly executed tasks so do not hurry in submitting and getting accepted.
Thanks and regards,
Amitosh S.
