Biology Subject GRE and low GPA

[paradisaeidae]

I have a mediocre GPA (hovering right at 2.99, although higher in last two years, and 3.5 in my major) and I will be applying to grad schools for a MS degree in biology, ecology, marine biology, or evolutionary biology. 

 

I know that the subject GRE in Biology is not required - but would it be beneficial for me to take to kind of make up for a low GPA? I would only be interested in taking it if it would actually bolster my competitiveness (and I think I could do well on it). 

 

Any info would be much appreciated! Thanks

For marine bio it will depend on the program as some I have looked at recommend it as one way to bolster the application and others will not accept it for any reason.  

 

Just so you know, the GRE subject tests are only offered three times a year; one date in each month of April, September, and October.   The next biology subject test is not going to be offered until April 18, 2015.
