How can I get a Copyright Transfer Form without notifying my advisor? My case is that we already have an adviser. She's not allowing us to register for conference (rank B). We have prepared everything after getting acceptance letter. Now she's telling us to submit the work to another conference (ranks A*)! We are pretty much sure our paper will surely be rejected if we submit it there and since our undergraduate study will be completed within 2 months we may not ever get this chance to publish a paper!

What should i do? She's simply not ready to listen. As she was the one submitting everything program committee will send eCF to her only. Should I write to the program committee so that he sends me an eCF? I don't want to change author names... just want to publish the paper!
This makes me sick (sorry). While I may understand your motivation and enthusiasm. But   betraying your co-author is not an acceptable solution. All co-authors need to agree on when and where to submit. Most likely, she knows better than you where the work should go. Moreover, If you planning to continue research after graduation it is better to keep good relation with her (at least you will need a recommendation letter written by her). You can continue your hidden game but no one would guarantee the outcome. She may even ruin your graduation. You need to have an honest discussion with her and make a decision. Tell her why you want to publish. No games. People tend to publish years after doing research/graduation.
