How to catch up on my studies?

This is how I study:
>Read notes (either my own or lecture slide printouts)
>acquire past exams and answers
>practice the exam, using the answers when I get stuck

Then once I'm familiar with the topic I do the whole exam without looking at the answers. This works well for me.

Ask your lecturer for practice questions and discuss how they got the answer if this material isn't available.

Yeah, I just finished a practice test today but that was the only one that was posted up.

I guess I should ask for more of those.

Oh shit I misread your first post (I thought the image was just a joke).

I'm actually working on my masters in chemistry right now; what part are you struggling with? I'm kinda bad at physical chemistry (it wasn't a requirement for bachelors) so I may not be so helpful with that.

I'm mostly struggling with formulas and all that. I'm doing really well in bio so it's definitely not the memorizing.

I'm in my first year and it's a core requirement of many of my subjects next year. (I'm taking Forensic Science)

I guess memorizing formulas should be my focus. Problem is, unlike maths, I can't find a place where all the formulas are just there in a list. And even if I do get a formula, I don't know how to use them since they're all used for different things and have their own symbols.

If you could find me a collection of all these formulas and a short explanation of each of them, that would be really great.

That's a really broad question, are you talking about chemical formulas or things like n = m/M?

What sort of questions are you being asked? A course outline would be helpful.

This is what I'm studying: http://www.deakin.edu.au/current-students/courses/unit.php?unit=SLE155&return_to=%2Fcurrent-students%2Fcourses%2Fcourse.php%3Fcourse%3DH315

And yeah, I'm struggling with formulas such as finding the pH of 100mL of 50 moles of Calcium, something like that.

I can't find a more detailed course outline so I'd have to follow up on all the lectures to make a list for you.

50% in practicals is the passing requirement for this unit, and I've done 2 practicals so far out of 10, and my average for those two is 32.5% which means i need an average of 62% for the remaining practicals. It's difficult for me since I can't look at the textbook during practicals either.

>pH of 100mL of 50 moles of Calcium

Okay this doesn't quite make sense, did they mean calcium hydroxide or calcium carbonate? pH is a measure of H3O+ ions in solution, so it's not a constant value and will vary based on concentration.

I rewrote this post a couple times trying to simplify it, so take what I've written below to try answer the question

>Find Kb (this value lets you know how much OH- you'll get from your species)
>Work out amount of OH- as a concentration (how many moles do you have divided by volume of water, express as moles per litre molL-1)
>Use log formula (it might be negative log) to get a number between 1 and 14
>this is pOH
>14 - pOH = pH

This is acid/base solution chemistry, youtube tutorials might help.

It's 2:28am here, so if this hasn't helped drop me an email at my throwaway email and I'll try get back to you in the morning [email protected]

All things considered, it might be a good isea to try going to class.

>>17489363
Yeah, I've started attending class now, but I'm unable to follow half of it due to the classes I've missed. The reason I didn't attend chem in the first place is because all their classes are at 8AM in the morning.
