I am a repeater so I had this self made dams notes since 2 years

I have a doubt…
I am a repeater so I had this self made dams notes since 2 years but now those seem old and for an update I bought new notes in November.
Accordingly I studied them but now I feel I messed up because I wanna keep reading my old notes and the new ones too and it’s causing me a lot of problem in terms or memorising and revision.
How should I go about?

I have 2-3year old notes and there is no difference in new notes so dont worry …

Only some update in psm is there rest all subjects are 95% same

Same with me bro…I have 2 yrs old dams notes…i was also confused… but after discussed with some frnds i decided to keep reading only those old notes …for Rest of the updated material, marrow is best…so no need to mug up with old and new jst follow your old notes…

Rest is up to u.
