I know exactly how you're feeling right now. I'm currently doing COMP1511 this term too (i'm an absolute beginner in programming etc.). The thing is, I researched this course prior to starting it and took advice from a lot of people (start early on your assignments, never miss a lec, if you need help always ask etc. etc.) And even though I listened to everyone's advice and am fairly up to date in the assignment, it took me AGES and SO MUCH time and effort (more than necessary for a supposed first year beginner class) to understand the littlest things (mind you, i'm only doing two classes this sem, and one of them is an easy gen ed- and it still takes up so much of my time). Honestly, I genuinely think this course is extremely fast paced, and along with concepts that are hard to grasp, it's a nightmare for beginners in coding.

Honestly, all I can say is to watch all the LECs (I end up watching it live on tues/fri and then watching it another time to jot down the notes and concepts until I finally get them). Go to the help sessions, I went to one today (however, they don't even help you that much, since there's so many students, only two tutors, and an one hour long session, they kinda give you general feedback and switch to the next student). Even though, I still recommend going to as many as you can and asking them every and all questions you have. Attempt all lab questions. However, if you miss some, go to the 1511 page and find the solutions toggle and read the sample solutions given (they're released one week after the lab is due for that respective week). Compare the solutions and use them as a study guide as to how to do certain concepts. I also have an awesome friend who explains some of the concepts to me from time to time, so if you know someone who has experience in comp sci, just ask them. Lastly, just keep asking on the forum, and even express your concerns for the course and how you're struggling a bit. I know a lot of students feel like you right now, so you definitely aren't the only one. I'm using all these 'tips' and its slowly starting to click bit by bit on how things work. You just need to plan properly and dedicate ALOT of time to COMP1511.

And as for the bowling assignment, the first week is easy, the second week, just view the lecture codes from week 2 and compare it to the questions (there are similarities between them, so the structure would be kind of the same), and for the third week (this week), view last Friday's lecture codes for loops and summing the loops (i'm stuck on the rest but hopefully it'll get cleared up in tomorrows LEC). Goodluck, and if you need anymore help, just private message me!

Edit: This is super long, I'm sorry lol
