Quit or accept the position?

I am a full time student and since my last post on a different subreddit, me and my job have been going back and forth. To sum it up, I am a full time student and now that courses are becoming more rigorous I was struggling to work full time. I accepted a position on 3rd shift which on paper looked really good with my schedule but it has been the complete opposite. I was offered a job back on second shift but it is a pay cut and is still 40-45 hours a week. Should I give the position a try or decline it and look for a part time job? Second shift originally was manageable but still very hard.
