I started learning Kanji but some of them have quite a few meanings, I can remember some but remembering all is difficult. Should I make sure I remember all of the meanings before marking correct, or is it alright to mark correct if I only remember a couple?
When they're related, you can just memorise one or two of them. For example, 集 has "gather, meet, congregate, swarm, flock", but you can just learn "gather" and maybe "meet". I wouldn't waste time trying to remember "flock" or "congregate". You just need to be able to "picture" the general concept.
For 使 you have "use, send on a mission, order, messenger, envoy, ambassador, cause", but you can just learn "use" and maybe "messenger" or "ambassador.
You'll learn the more common ones through vocab anyway: 使う (use), 天使 (envoy/messenger), 大使 (ambassador).
Some of them are really low-priority, e.g. "seventh sign of Chinese zodiac" for 午.
