Here are some reminders of tips for preparing for the quizzes. If you're already doing many or all of these tips, that's great:
Log on the Google Meet five minutes before the start of every class. (In fact, show up five minutes early for any appointment instead of showing up exactly on time or after the meeting time.) It's best to be ready and prepared to learn as soon as the lesson begins. This way, all presented information is learned and not missed.
Pay active attention to the lesson as best as you can as if you're attending class in person. (Don't just log on for attendance, then pay attention to other things like social media through the lesson. Don't just plan to watch the video lesson later when you can learn the information in real time, the first time.

Have your notebook ready and jot notes during the lesson. This way, you're learning actively and ready to ask questions in real time if you have any. Don't just passively look at the screen and listen as if you're watching television, expecting yourself to relearn the material later. Focus on the lesson and try your best to understand the concepts the first time. This, way, you can use your follow-up studying time reviewing concepts instead of learning new concepts.

Before the lesson, read the assigned pages in the textbook as well as look at the class notes. (They're identified in the daily H.W. on the calendar.) After the lesson, read the assigned textbook pages again. By reading the same information from a different perspective, the general concepts of the lesson are better understood.

Hopefully by now, students have a routine established of completing at least an hour or more homework per subject outside of class time. (In other words, attending online classes is not the only time to be learning science in the day.)
When preparing for the quiz, study as if the format of the quiz is closed-book. Student days well before the quiz date, not the morning of the quiz. Don't take the opportunity to use resources for granted and learn the actual course material during the quiz! This approach creates unnecessary stress during the timed quiz, so avoid the approach at all costs!
Students who are doing very well on the quizzes are telling me that they are engaged in all of the above suggestions. Students who are doing poorly on the quizzes are not engaged in the above suggestions. If you fit somewhere in between, do try to change your routine to best put yourself in the position to learn optimally and maximize your success.
