Hi,
The first tip: Never have any negative beliefs. You saying to yourself that you most likely are not her type will screw you up without you even realizing that. Your beliefs are such powerful things that determine everything you say and do to women. They either set you up for a success or for a failure.
To fix your belief, I recommend that you watch out for my reply to this thread:

The second tip on how to ask her out: Make sure that whatever you say to her always sounds like
it's really not a big deal to you whether she accepts to go out with you or she doesn't.
An example for asking her out after college:
'Let's go watch movies at my place.' or
'Let's go to that Beatles show that you've ben dying to see.'
Anyway, knowing how to ask a girl out is often not enough to guarantee you a success in getting her laid if you don't have the right dating strategy and the right dating logistics as to choosing the right public place to meet up at and knowing how to bait her to come over to your place afterwards.
One of the key things that you should keep in mind when asking her out is that you always choose a public place to meet up at where you two can sit side by side so that you can be smoothly touching her. This is one of the main reasons why dinner dates suck. They suck because you're sitting across the table away from her and you can't touch her at all.
If you want to learn more about the right dating strategies and the right dating logistics when asking her out, I suggest that you check out the chapter about those topics that I go into on my blog's page about overcoming her last minute resistance - LMR at:

Hope this helps you.
