To check your weighting to equipment ratio at the surface, hold a breath and dump the air in your bc, if your eyes are at surface level you are properly weighted, if you sink below mask level your overweighed and visa-versa. When you are properly weighted you dump and exhale and should have no problems on ascent. Check with your instructor on a peak performance buoyancy instruction, sometimes part of an advanced certification. Remember to relax and enjoy the diving experience. When you attain proper buoyancy there is no experience like it other than maybe being an astronaut in free-fall, enjoy....
