Online Courses

[StHoly]

Hello~

As the wait continues, I am 80% sure that I won't be getting into any grad schools that I applied this season. So I will be lookin for a full time job maybe in February. I actually do not wish to re-apply anymore, as this is the 4th application cycle for me. I do not want to take GRE anymore as well. I know there are many schools now that are accepting applications without GRE but the schools that I wish to get into, where their research is a perfect fit for me, requires GRE. I am feeling dejected now since it feels like what I have done the past 8 years (all the research and a master degree) would not amount to the shitty undergrad GPA and GRE that I have. 

My question is, do you think taking online courses on some programs that I think I"m lacking, such as some engineering introduction classes (I"m a chemistry major with a biotech master) will help with my applications in the future? I believe I have shown that I have the resolve to stay in the research industry since in my SOP I've mentioned the work I've done over the past 8 years. I was a chem major, but I wanted to switch to more biomaterials/ biology so I've tried my best looking for opportunities (research for Masters, and internship) to what I wanted to do. I do believe the fact that I am lacking engineering classes is one of the biggest factor that I was not able to get into BME school, aside from shitty GRE and undergrad GPA. My master GPA is as good as it can be (>3.8/4.0) 

I am planning to take online courses, and get online certification. I want to show that I am indeed interested in this area of research and wish they would give me a chance. 

What do you think?
