Study hard. Go to class. Do homework, and a lot of practice questions. There are exceptions in chemistry and you need to make sure you study those. Be a good student and you will get good grades.
Mr. Williams is a pretty good teacher. He has his good days as well as his bad days. His lectures are actually really informative but he doesn't use slideshows, he uses jpgs he never shares and drawings he does on the white board. His tests arent as hard as people claim them to be, the only way you'll do well in his class is regularly doing the homework. I did the homework almost everyday and I got a 91 midterm and 94 final. At heart, he's a great soul and he'll bless you if you have him second semester in grade 12. I love you!
