Can I complete the junior and senior years of Army ROTC with BCT & AIT being done by February?

MAJ Javier Rivera is right that you should ask your PMS at college campus for exact details. If memory serves, BCT and AIT can waive freshman and sophomore years, but junior and senior years have to be done on campus. You also have an unrelated ROTC camp in between your junior and senior years that serves as a standardized test for military proficiency and OML purposes.

That's a question for the school's PMS, or its representative. Perhaps a call to their office would suffice.

DM me.
