Just go on with Unit 3?

[dekoyl]

Is it okay to just go on with unit 3 if there are things in units 1 and 2 that needs brushing up on?
For example, I've forgotten most of unit 1 and still a bit unfamiliar with redox chemistry.

Can I go on reading Unit 3 stuff and pick up the necessary knowledge on the way (or is this not a good idea as a very well established basic knowledge is required)?

Thanks

Yes
If you're using the heinemann book they have revision chapters on what you need to know anyway(acid/base, redox, basics).
I got 54% in my unit 2 exam and got an A for unit 3.
You don't really need anything from unit 1 anyway :S

Because I've got this book that's meant to prepare you for unit 3/4 and it's got so many things from Unit 1/2 (probably everything) :S
Made me wonder

unit 1/2 is very important to 3/4, but not as explicitly like physics

the foundation set up in 1/2 is critical for proper understanding of concepts in 3/4

Huh? Are you saying you have heinemann? If so you will be fine, it will all come back to you anyway and if you have any questions just ask people on here, it will make sense, trust me. I was lost when I started unit 3 as well, and the fact that you have more motivation than I ever had reinforces my opinion .

Would you say everything in units 1/2 is very important? There's time but I'd rather not read through a whole year's worth of material again (sounding a bit lazy, I know )

Thanks for the reassurance. Hope you're right

no, that would take too long, but knowing 1/2 would be very useful. Just go on with learning, and if it doesn't work so well, hire a tutor.

I wouldn't recommend that you spend time reading unit 1/2 stuff =_= more than half the stuff is irrelevant, and stuff which does help you either go over again in your book or just gives you a tiny amount of insight as to why some things are what they are.

You should've made notes for the Unit 1/2 stuff But I don't think there's any point revising stoich, everything is covered in the first couple of chapters of a textbook for 3/4. If you want to revise atomic orbitals/subshells it might be worth it because there's a bit of that in spectroscopy

Ah great, thank you. Fortunately I still remember the orbitals and subshell stuff.

oh and galvanic cells would be useful to revise for Unit 4, but again, your 3/4 textbook should cover what you need to know anyway

omg i got a 52% in my unit 2 exam
lol--> nasiolous was interrogating me cause i got her hopes up.
does that mean i can still get an A in unit 3 exam?

You haven't even started the chem 3/4 course yet, anything is possible, including A+
