I had a good system for matric, so I'll share it. But it's kinda long, so I'll try to be brief. 1. English - Identify the sections and only do exercises from the internet. I catagorized them under Grammer (had sections like Tenses and Verbs) and Comprehension (had sections like Reading, Writing, Vocabularies). 2. Bio and Civic - I studied one chapter of Bio in a day and 3 chapters of Civic in a day no matter what. No excuses. And then before I study these subjects again, I revise the previous chapters. Each time I study again, I revise all that I studied before which helps a lot with memory. 3. SAT - Only do exercises from previous matric questions. I got them from Key Reference Book. Pro Tip: Focus on the questions that came out 4 or 5 years ago. They're the ones that will be repeated. 4. Chemo, Physics and Math - ደረስን ወደ ጮማው። These are the toughest and most demanding subjects. I advise you to start studying ASAP. ዛሬ፣ አሁን። Believe me, even 3 months isn't enough to cover these. You need to constantly do exercises from every chapter, read on theories and watch YouTube vids for help. You can't sit and read for these, and expect to be ready. So start ASAP. The quickest way you can do this is read chapters while doing exercises. I know I make it sound scary, but it's only scary if you're not ready. Even if you know 60% of each subject, you will get above 75%. Extra Tips: 1. Schedule - Making a plan is very helpful. It might be overwhelming, but it makes the process easier and more focused. 2. Hybrid - When you study, make sure there is variety. After you study a subject for a while, then study 5 others before you get back to it. This is my tip. I hope I helped and I hope you get a great result. Good Night 🌃
