Mbbs completion

My child had taken admission in MBBS in year 2012 in Pvt Medical College. She is in Final year and is left with 2 papers out of 4 to be cleared . In 2016 onwards she is under medical treatment and could not pursue her studies effectively due to which she got further delayed in clearing her papers. At that time when admission was taken I understand there was no time period to complete the course. ie no maximum tenure in years was defined. In NOV 2019 National medical Commission (erstwhile Medical Council of India) came out with amendment with 10 years of period to complete MBBS. Now I would like to know if such amendment dated 4th Nov 2019 is applicable to my child since she took admission in year 2012. The new Act says it is effective from date of publication. If Yes then what is the legal remedy if my child is not allowed to take exams for completing her course. This will have setback to the child Is there any petition elsewhere in India in any court to challenge this amendment for such students. Need guidance
