Can i redo the tasks here ?

That's a good question, I was actually wondering the same thing. I looked in the FAQ for it and found nothing helpful.

Wait for a new task avaiable from jobs maker. I you have completed your taks and already submit yours, in next time you will notice as privat mesagge whether your tasks is approved, returned or rejected. If your tasks approved, your earn will increase as amount as they awarded. If your task returned for some reason that raised by them, you can edit or 'do this' task again, submit and wait for their approval. If your task rejected, you have now idea expect you have another new task that will given next time.

Sometimes there is more than one opportunity to complete the same task. Of course now the tasks are on hold so there is no telling what they will be like when the new tasks begin again.

why you want to do this if your task is approved , i suggest to not do it again , it can also lead banning of your account. aakansha : as your name reply that you have aakansh to do , but pls avoid such silly mistakes. just enjoy your life here on other new things that are comming each minutes.
