MBA programs ask for all transcripts and grades

I know most MBA programs ask for all transcripts and grades after high school. I am a very good student with a 3.8+ gpa, great extracurriculars but the only issue is that I’m taking a summer course at university near my home and I’m not doing well in it at all. I don’t plan on transfering it to my university, if I don’t transfer the credit and it doesn’t count towards my major could I get away with not submitting it to any of the MBA programs.
