After solving a problem correctly on your own, compare your method to the solucionario’s anyway. You might discover a shorter, more elegant way. That is the mark of a future mathematician.
Treat the solucionario like the solution manual for a video game level: look at it when you are truly stuck, learn the pattern, then replay the level on your own. That is how you truly pass—not just the course, but the test of mathematical maturity that Bachillerato demands. solucionario sm matematicas 1 bachillerato
