He could claim one more allowance, if you qualify as his dependent. If he will be claiming a tuition credit, he could claim even more allowances.

But, he may not be able to claim you at all. There are two types of dependents, "Qualifying Children"(QC) and
standard ("Qualifying Relative" in IRS parlance even though they
don't have to actually be related). Only a QC qualifies a taxpayer for the Earned Income
Credit and the Child Tax Credit.
A person can still be a Qualifying
relative dependent, if not a Qualifying Child, if he/she meets the 6 tests for
claiming a dependent:
1. Closely Related OR live
with the taxpayer ALL year
2. His/her gross taxable income for the year must be less than $4150 ($4,050 in 2016-17)
3. The taxpayer must have
provided more than 1/2 his support. **
In either case:
4. He must be a US citizen or resident of the US, Canada
or Mexico
5. He must not file a joint
return with his spouse or be claiming a dependent of his own
6. He must not be the qualifying
child of another taxpayer
**The IRS has a worksheet that can
be used to help with the support calculation. See: http://apps.irs.gov/app/vita/content/globalmedia/teacher/worksheet_for_determining_support_4012.pdf The support
value of a home is the fair market rental value, divided by the number of occupants. If you have student loans or scholarships, that is support that your BF does not provide and counts against him being able to claim you.
