There are heaps of self study materials availabe.
Three books I religiously use for the rest of my life are not in print anymore but availble second hand still.
Shotokan Karate International Kata, Volume 1 (1981) ISBN-10: 4262168514
Shotokan Karate International Kata, Volume 2 (1982) ISBN-10: 4262168522
Shotokan Karate International Kumite ISBN-10: 426216201X

SKIF stdents continue to struggle to memorise all the Kihon Ippons and Jiyu Ippons.
Google "Kihon Ippon SKIF" or "Jiyu Ippon SKIF". There are hepas of graphic materials as well as youtube videos online.
