Thoughts on level 4 please?

Cat37

I've completed level 3. I am wondering if I should continue to level 4....
I have the finance to do it and I know I will be pleased. I am concerned about the effect on family life and how much more is involved than level 3.
I spent one day a week in college and several hours homework. This doesn't sound like much however I also work three days a week and have a dependent family. I am reluctant to bail out but wondering how much harder level 4 is and home much weekly homes study is realistically required.
Any advice please?

Thanks!!
