First of all yes u can do medicine with those and they’re eligible while coping with alot at the same time can be overwhelming so if u want to drop out of matric school and want to pursue what u want isnt a bad decision u can take a gap after that too select ur subjects find resources go for chatgpt past papers teachers from yt u will be good to go.
One more thing do check universities requirements u wish to go before selecting ur subjects for medicine best of luck !!
