Just do your regular work.
NO EXTRA CREDIT FOR INDIVIDUALS. Extra credit for you means extra work for me, and, frankly, I’d rather not take on this additional burden, which has been generated by your inability and/or unwillingness to submit your regular work on time. Therefore, I feel absolutely no obligation to set up extra credit assignments for individuals.
Also, consider this: extra credit opportunities reward slackers and discriminate against students who submit their work in good order and on time; therefore, I don’t arrange or accept extra credit assignments, unless I do so for the entire class, so don’t even ask.
If you keep up with your work, you don’t need to do extra credit work.
