These are officially released Regents exams from every administration period. This a great practice source if you are preparing for any Regents exam.
If you have class with Minghan, here are some notes created by Minghan for some of his classes.
Excellent resource for studying. There are so many courses on there with lessons and practice questions. Personally, I used it to study for the SAT and I found it very helpful especially since it's officially affiliated with College Board.
The AP Calculus exam has non-calculator sections. Sometimes, practicing arithmetic skills can be very helpful in such cases. There are tons of drills you can do for different skills and operations.
If you missed anything from school, or need lessons from a different perspective, try using Flippedmath for your math classes. There are guided notes with a teacher video. However, some lessons are paid for some classes.
This one is more for teachers. There are premade lessons with accompanying videos and answer keys. There are also unit exams. Their lessons are challenging and require critical thinking.
APlusPhysics is very helpful for physics courses, especially Regents physics. I personally loved using this website to study for my Regents physics test. There are Regents practice questions sorted by topic. However, you need to purchase the book to have the answer key.
This one is for my anatomy and pre-med students. Great interactive diagrams and models for the different systems you are learning about. The only downside is that this is more of a paid platform. You can get around it for some of the models by just ignoring the message asking you to log in.
