Rules don't seem clear to me

Question

I am a bit confused here. Below are two responses which I got wrong. In both cases the "hint" is that it is a "future idea". So why should one of them be indicative and the other subjunctive? "Even if you don't want to" I put in the subjunctive because there seemed to be a bit of doubt, and that was marked wrong. "Even if you do extra hours" I put in the indicative because it seemed that that was definitely going to happen.

I think this is a very complicated and nuanced piece of grammar so I would appreciate some help, thank you.

PS I tried to include a screenshot of my answers but the system wouldn't let me.

Hola Barbara
In the question with quieres/quieras you need the subjunctive as it's a expressing something that may happen in the future, i.e. that he/she doesn't want to go - I checked that the system had as correct answer "quieras" using the subjunctive. I also checked what you answered to this question and I can see that you got that question on your test that you did at 14:42 hours on 2nd Jan 2024, but you answer with the indicative "quieres", not the subjunctive "quieras". 
On the other one with "haces/hagas" you also need the subjunctive "hagas" but you answered with the indicative "haces". This is still expressing a future idea as it says on the hint. You got that question on your test at 14:46 on 2nd Jan 2024.  If you re-read the question, you'll realise that this is something that "will happen". If this was something expressed as a "fact" we would have probably used "Even though you do... " expressing that this actually happpens, that is what you actually do.

I hope this clarified it. If still unclear, please let us know.
