I don't have very efficient memorization techniques and mostly rely on repeated readings! But here are a few things that I can suggest.
1. Spaced revision- Not letting anything go unrevised for too long.
2. Memory pegs for lists [Duties, Articles, Schedules]- Remembered them from a Roman Saini video 4-5 years ago and haven't forgotten since.
- 1=sun, 2=shoe, 3=tree...
3. Finding linkages- If I read 'X' from a booklet in my notes, then I note down every important thing that I know about X on the side of the page. Doing this repeatedly creates good linkages and the topic gets revised decently every time I come across it in difference places in my notes.
4. Finding Patterns- Constitutional articles jump from center→ state by following
-Rule of 89: for Art (72 to 88)- {80, 82} and Art (99 to 111) - {108}
-Rule of 90: for Art (112 to 124)
5. Mnemonics [It'll work as long as it makes sense to you]
-MP ON KD: WtE for protected areas of NEI [Manas-Pobitora-Orang.....]
- NtS order- Astana, Bishkek, Tashkent, Dushanbe, Asghabat | AsBiTaDu As
- Buddhist councils-
RVPK- Rajgir Vaishali Patna Kashmir
AKAK- Ajatshatru Kalashok Ashoka Kanishk
6. Using brute force- Repeating the order in my head till it makes sense
- NtS→ nallamalla velconda palconda nagari seshachalam javadi shevaroy panchmalai sirumalai palani
7. Using Maps/ Diagrams- Way easier to remember visuals/ images/ numbers than words
Eg-
8. Explore Method of loci- At the moment, I can recall ~first 100 digits of PI using that method. It's not UPSC related but it definitely works for small lists of 10-15 items
9. Use Google maps to your advantage-Plot stuff and see the locations relative to other places. .
Eg-
Can u link the video u talk about in point 2?
