Respected sir & madam , I am an intern. I had purchased MARROW Plan C

Respected sir & madam , I am an intern. I had purchased MARROW Plan C in mid 2020 focusing my aim on “NEET/NEXT 2022”.I had watched videos of 3-4 subjects one time ( EDITION 4) keeping myself one step forward for exam. ( Eg, general & haematology of Pathology , whole of surgery, G&O ,ENT, psychiatry, orthopaedic, & some part of pharma )
Now, MARROW has launched EDITION 5 with clinical core focusing mainly on 2022 exam. It’s pretty well. But every faculty have updated & recorded their videos newly . I welcome it. As I had watched the EDITION 4 videos of these subjects & now these videos are with new information , new style , these videos are totally new to me.
If I now start to watch all these 3-4 subjects’ videos , more time will requir & reason of purchasing it in mid 2020 & all invested time of watching will go in vein. My 5-6 months of preparation during hectic internship duty will be worthless.
What should I do now ? should I rewatch the edition 5 videos or stick to edition 4 videos ?
I am stuck in between , neither I can watch edition 4 videos as it will be worthless as new videos will come ,nor I can watch remaining new videos due to unavailability.
Please guide me. What ahould be my strategy focusing 2022 ? ( NEET 2021 Can’t be cracked by reading only 3-4 subjects)
P.S. - “Marrowlings” didn’t approve my post,I don’t know why . So I post it here.
