<p>I'll be a freshman at UMD this Fall.</p>
<p>I intend to do a double major in Mathematics and Computer Science, but not pretty sure about it.
Enrolled for Computer Science at the moment.</p>
<p>My Orientation is on 28/29 July.</p>
<p>Not sure as to whether my adviser should know about my double major intentions just yet. Is it OK to register for regular classes for the first year and then decide on the double major later?
If I decide on it after the first year, then are there any drawbacks?</p>
