These are my sentences.
This week I've been busy preparing for my test.
I study 5hours and do the household chores about two hours every day.
For the rest of the time I just take it easy, watching TV or reading.
I'd like to know if I can change "for the rest of the time" to "otherwise" or "other than that", like "Otherwise I just take it easy." or "Other than that I just take it easy." I did research myself, but I wasn't sure about it. Could you explain it, please?
