People like me are why I believe the slippery slope is a fact, not a fallacy...

I'm asking this in the context of a school project mainly because of 2 things:

1: 2 of the questions of the project are about main and secondary characters and their physical and psychological characteristics, so the book is gonna require those unless I'm misinterpreting those questions.

2: The project is for March 12th so something like 1984 with 300+ pages is probably too long. (Although there are probably many technicalities to blur this, like how much text there is in a page and the actual amount of pages I can read in a given time and how much time can I dedicate to reading the damn book.)

Ok I'll start:

Brazil: here the schools are split between the fundamental level, which is 1-9th grade, which is then subdivided onto fundamental I and II, which range from 1-5th (ages 6-11) and 6-9th grades (ages 11-15) respectively. Then we have 'medium' level ("Ensino Médio") which goes from 10th-12th grade, and then we have a national test called ENEM, where everyone takes a test to be able to enroll in the many colleges/universities which accept it, where you then reach 'superior' class and take technical courses and the like.

Class goes from 7-12:20 Am for fundamental II and 1-5:20 pm for fundamental I. This is because each day is divided into six periods of 50 minutes (+a 20 minute break, like in most places) for the sake of making subject distribution easier.

There are 8 subjects in fundamental class, Portuguese (grammar), math, geography, history, science, physical education, English (still mostly grammar) and arts. (Unsurprisingly it's more about culture & music than how to draw)
In 'medium' class, 3 more subjects are added, which are biology, physics and chemistry.

Funding for education is reserved for the states to decide, although it usually goes from 15-25% of total tax revenue.

I'm in my early 50s and have been seriously considering going to school. I have performed manual labor for most of my working career, and though I truly enjoy it, my body cannot keep up anymore. A few years ago I began looking for work in an office environment, and after a a demoralizing year of submitting resumes, I landed a minimum wage job in a small customer support office inside a larger organization. The work was soul suckingly boring. I applied to other departments and received job offers, but management would not let me leave customer service because I have a way of deescalating difficult situations. I was eventually offered the customer support manager role, but I refuse to manage people. Since the company would not let me move out of customer support, I left them and took a long vacation. That is where I am at now.

I am afraid that an educational investment will not pay out the dividends that I am hoping for. I don't have all the time in the world anymore. I guess I am looking for career / school advice, or if not advice, similar journeys.
