Complete Astronomy for NSEA & INAO

NSEA and INAO don't test astronomy as a side subject — they test it as deeply as physics itself, and most students underestimate that until it's too late. This course is built to close that gap in one pass: every topic the astronomy sections of NSEA and INAO actually draw from, taught from first principles rather than assumed.

Starting from the celestial sphere and basic coordinate systems, you'll build up through time systems, orbital mechanics, stellar physics, telescopes and optics, and enough cosmology to handle whatever the theory paper throws at you — each recording followed immediately by a problem set in the exact style NSEA and INAO actually use.

By the end, astronomy stops being the unfamiliar section you're least confident about and becomes the one you're most prepared for — every question type in the astronomy portion of NSEA and INAO covered, derived, and drilled.
