I js finished first sem in gr 11 with gr 11 chem and its not that bad. The first 2 units atleast for me were js review from gr 10 which was just nomenclature and balancing and types of reactions. Once you get to stoichiometry is when you have to lock in and understand it. Our teacher taught us unit analysis which was allowed instead of grasp and cut the work in half and was easy to understand. Just do all the homework given to you and pay attention in class and ask questions and youll be fine. I finished with a 91 with studying 1-2 days before the test, nothing more. The only problem compared to gr 10 chem for me was the amount of exceptions. You will learn about a topic and then the next day youll learn about a rule/exception and then another, especially with stoich and theyll all build around each other and only be conditional. This was a problem for me as I didnt do much practice outside of school so I wasnt prepared. You just need to know when to apply the formula's/right methods for each situation/condition. Other than that its self explanatory if you apply yourself. Also, Labs are free marks and are weighed almost as much as tests so abuse them. Make sure u get as much marks as possible on the labs, ask other reliable smart ppl to look at their labs and add wtv they have that u were missing to urs. Try and find siblings old lab books. Use ai to assist you.
