In most works of fiction with school-life settings, the place will often function as a stage for romantic melodrama, violent gang fights, rape, bullying, suicide, sports, fun, laughter, friendship, zombie invasions, large-scale conspiracies, apocalyptic wars... In other words: anything but studying! 🤣
Dragon Zakura takes the unusual route. Ryuuzan is an ordinary (albeit rather sub-par) school with inattentive, underachieving students and less-than-devoted teachers. It's interesting to follow the protagonist's attempts to produce Tokyo University graduates from this miserable excuse for a high school. I do find his motive a tad unrealistic -- and as of yet not much has been explained about why he'd choose that particular route -- but hopefully this'll be cleared up with time.
The study methodologies outlined here are actually quite effective, and will work well regardless of subject or standard of exam. I really approve of the realistic views on the role of education in everyday life that are being put forth here -- it's something most people don't seem to have realized even in today's digital era.
The only major drawback is that the art isn't very effective at conveying emotion. The nature of this manga is such that it requires skillful illustration of facial expressions to provide an appropriate mood to the story. Still, it'd be a shame to pass up on the series for that reason.
