Uphill riding hard for me
Basically the only real way to get better at going up hills is to get fitter - which you can do by repeatedly riding the hill :-)

Some tips:


Stay sitting down
Use low gears and a fairly high pedaling cadence
Use good gear management, shift down progressively as you start the hill and keep pedaling cadence up. 


The main point is you want to avoid using your anaerobic system and exhaust your legs. Pedaling too slowly and too hard will make you go anaerobic. Low gears and faster pedaling will keep you aerobic longer.
