CommonApp Activities and Language Proficiency?

<p>Hi everyone! I have a couple questions regarding the common app.</p>

<p>For the activities I only have 3 ECs/activities that I spent quite a lot of time on. Would it be alright to add an activity that I just started senior year? So far I have spent 17 weeks on it, usually 1 hour per week (6 of the weeks I spent 2 hours). I know that you shouldn't be adding things that you aren't committed too but I'm planning to continue this throughout the year and do something similar at college. It also relates to what I want to major in. </p>

<p>Also for the weeks spent per year, do I put the actual amount or the projected amount by the time I graduate?</p>

<p>Last question: for language proficiency does that include languages studied at school? I've studied Japanese for 4 year at hs and 3 years in middle school. </p>

<p>Sorry for the long post >>'' Thank you so much!!!!</p>
