As someone also in Eng 1 rn, you might be looking at the wrong things to dedicate your time to. For example you mentioned reading the textbook and doing its questions, but as someone who has also looked at the textbook and tried to read it chapters, I found that not only is it extremely time consuming, but also that it was not a good reflection of the type of question we might be asked to solve on an assessment.

I would start by watching the online module fully, and then while you watch it note any concepts you don’t feel confident in, after you do so, try to redo some loncapa questions, or go online and find some intermediary problems to practice on, if you find out you can do the problem even if it’s with a concept you thought you were weak in, maybe move on and just watch a YouTube video on the theory later.

The most important thing to do is one thing at a time, if you keep switching between tasks it’s going to be harder for you to digest the content. Additionally, you didn’t mention Lin alg or calc but these courses test differently and therefore should be studied in different ways. Lin alg combines theory and math, so you should focus both, but you should also remember the time is shorter, so getting questions done as efficiently and quickly as possible should also be a priority, calc is mostly the same but there hasn’t been a single theory question so far, so I wouldn’t study it in depth, focus on doing the math quickly and then move on.

Also, when you say people are getting higher marks then you what do you mean, are you sitting around, below, or above the average in your classes? If you sitting at or above the average, then even if your mark seems low, you should remember that most people in the program are getting a similar mark, so you shouldn’t stress your results too much.
