hello friends, I have 290 in my GRE and 87 in TOEFL and have applied for maryland university,college park for electronics and computer engg, Illinois Springfield for data analytics, uhcl and Monmouth university for MIS. I have 10 months of work experience but the issue here is that I cannot get a letter from my company to show that I work there bcoz I haven't told them about my plans for MS because it is too risky. so all I did was I submitted my resume to all these universities mentioned to show that I have work experience. Is there any other way to tell all these universities? also do I have a chance to get into these universities? and please suggest me some more universities thank you
