I've recently begun learning Spanish, and while I'm gaining a good understanding of vocabulary, I can't seem to find many effective resources for studying the grammar, without having to pay a lot of money. As a student, I don't have money to spend on textbooks so I would really appreciate your help! I have been using Lingodeer, which has quite useful grammar notes, but it also seems to go somewhat slowly.
Edit: I know I've come back to this post quite late, so apologies for that. To add some well-needed detail which will hopefully help, I am specifically looking for a website, app, podcast etc. with a linear curriculum of the basics of Spanish grammar.
For comparison, I am also learning Korean, using the websites https://howtostudykorean.com and https://talktomeinkorean.com, both of which offer well-organised curriculums for learning Korean grammar.
I would like a similar resource for learning Spanish grammar, if possible. However, if none come to mind, it would also be quite useful if someone could provide any kind of curriculum with a general idea of what order I should be learning certain grammar components in. This does not necessarily have to include grammar/vocabulary notes itself as I am okay with searching for those and/or making them myself. At the very least, I would just like a simple list of things I should learn in order to gain a strong foundation.
Thank you all! I hope the added detail helps at all.
