here are some tips that have helped me! (I've been homeschooled for 5 years)
Explanation:
First, stay neet. Have clean notes, use different colors, assign a color to each subject.
Next, make commitments. Set timers for every 30 minutes and every 5 minutes (I.e. 1:30pm, 1:35pm, 2:00pm, 2:05pm) this was you can have scheduled breaks and keep yourself in check as well as giving you something to look forward to.
Personally, I need music/movies playing while studying so that I can enjoy studying so I recommend having a playlist/tv show that you wont have to constantly change if this is you as well.
I use noise cancelling headphone to watch/listen because I have a noisy family so I recommend telling them you're studying and that you can't hear them and then zone them out.
We've all heard of the chewing gum studying tip, but I recommend chocolate. It has ingredients that access your memorpheliac parts of the brain!
Finally, motivate yourself. Make it a priority and keep reminding youself how important it is to get this grade! keep reminding yourself of your gpa and your future. Also, it could help to get someone in your family to explain topics to you. sometimes as young people we understand better when things are explained to us/showed to us.
I hope this helps, its just what works for me.
