Why don’t you ask you school’s guidance counselor. They will know how to offer you the best guidance. Fwiw, I would not take alg 2 DE bc it would be considered remedial, not college level.
Fwiw, I still believe you are going to face tremendous hurdles. Kids who graduate early and apply to college are competing for admissions with students who have had 4 full yrs to graduate. Adcoms will not lower expectations bc you opted for 3 yrs instead of 4. Students applying to the schools on your list are going to have much stronger transcripts. That is simple reality.
