Is the Yoga 7a good for note-taking in class?

Yes. The 360-degree hinge and touchscreen let you fold it into tablet mode, and pen support makes handwritten notes practical. The 16-inch size is less comfortable to hold standing up.

Only light ones. The integrated Radeon graphics handle older and casual titles at low settings, but demanding 3D games will stutter.

Is the screen good enough for photo editing?

It works for casual editing, but the LCD panel covers less of the color gamut than OLED laptops. Serious photo work benefits from a calibrated, wide-gamut display.

How does it compare with the Yoga 7i?

The 7a uses an AMD Ryzen AI 7 chip; the 7i uses Intel Core Ultra. Performance is close for everyday tasks, so pick based on ports, screen options, and the configuration available.

Does it come with a stylus?

Lenovo sells an active pen separately for most Yoga 7a configurations. Check the box contents of the specific model before assuming a pen is included.

Is 16 GB of RAM enough?

Yes for browsing, Office work, and light editing. Heavy video work or many virtual machines would benefit from 32 GB, which this model does not offer.
