Study shows that studying before sleeping is helpful in remembering what you learnt after you wake up. Learn before sleeping, and there is chance that you will remember the lesson better when you wake up. Even if you have a bunch of homework/work to do, if you decide to revise even just a few ayahs, Allah(SWT) will make it easier to complete your work.
However, if this pressurizes you, then learn the whole of Quran once and take a diverse course to understand it’s translation.
Keep on reviewing your sabaq so that you don’t forget it. If you feel comfortable, move on to another part. If you want to go further, learn a few more lines or another page. However, don’t push yourself too far. Learn how much is just right for you.
