How physics should be taught.
Not through static diagrams and long blocks of meaningless text, but through dynamic physical simulations that allow you to build an intuition for how physical systems actually work.

Improve your grades.
Rote memorization is overated. Build a genuine intuition for how complex physical systems behave, and learn to think critically and tackle problems effectively.

Finally, learn to enjoy physics.
Yes, physics can be a difficult subject, but that doesn't mean you should hate it. Overcome challenges, and experience the true beauty of physics.
