Summer Classes ENGR233 and COMP249

Hello i wanted to take COMP249 and ENGR233 For summer 3 (july to august) but i wasn’t sure if it was too much. I work 15h a week but wanted to work more hours during summer. If i don’t take ENGR233 ill have to take it in Fall and i already have hardes classes like Elec275 so it would help a lot to do it during summer

Does anybody know if it’s too much, if it’s okay to manage and still work more than 15h a week during that time? Thanks
