Failing Chem practice exams.

So the exam's three weeks out and I'm stressing like there's no tomorrow.  :-\

I started doing a couple of exams last week and did dismally. When combined with how horrible I just went on another, I think I'm screwed.

If I'm getting like 7/20 for multi choice and flunking the short answer, where do I go from here?

I've grabbed a notebook and am noting down everything that I'm getting wrong, but there's simply way too much!

Purchase a study guide, such as A+ notes or the ATAR Notes study guide (highly recommended), and read it!

Don't bother doing practice exams if you're not ready. Do some of the textbook questions, which are easier, and are good for reinforcing concepts.
Do some questions out of checkpoints and/or any study guides (e.g. NEAP SmartStudy, Lisachem).
Type up a summary of the course.
When you do practice exams, do them untimed until you can do them within the 90 minute allotment.

My advice: do not write notes.  Just keep reading the notes you have.  Draw diagrams, they help more.  Draw diagrams for the chemical reactions, in particular (i.e. the organic reaction pathways). Write down the mistakes you make, make sure you don't make them again.  Read your textbook. Read it again.  I think it's a bit late for studyguides (I started mine as soon as I started school) but when I first started the guide I lost all the marks on all the questions.  Don't worry, it happens to everyone, but I made more mistakes on studyguides than exams, because the questions are similar, and if you don't repeat the same mistake twice you'll be fine.

The thing about study guides is that they give you a really strong hold on the basics. If someone's getting 7/20 in MC, it's the basics they need help with.

i agree with charmanderp. Trial exams can only ever be so hard (they won't make it ridiculous) and you should just practise doing questions. If you're having trouble breaking questions down, u should get the AN chem book! Solutions cannot be anymore detailed :P

Adding on what the others have said, here's my opinion - just remember that it's my opinion, everyone's approach to study is different but this is what I would do:

The first thing is probably to not get overwhelmed and also realise there's still plenty of time. Break everything up into specific parts and approach it that way.

Take a look at the study design for the main topics, you should be able to take a look at every item and have at least some idea of what it's talking about.
http://www.vcaa.vic.edu.au/vce/studies/chemistry/chemistry-sd-07.pdf

I've copied and pasted them here:
Quote
AREA OF STUDY 1 - Chemical analysis
• volumetric analysis: simple and back titrations, acid-base and redox titrations;
• gravimetric analysis;
• calculations including amount of solids, liquids and gases; concentration; volume, pressure and temperature of gases;
• use of oxidation numbers to write redox equations;
• principles and applications of chromatographic techniques and interpretation of qualitative and quantitative data from thin layer chromatography (TLC), high performance liquid chromatography (HPLC) and gas chromatography (GC);
• principles and applications of spectroscopic techniques and interpretation of qualitative and quantitative data from atomic absorption spectroscopy (AAS), infrared spectroscopy (IR), mass spectroscopy, nuclear magnetic resonance spectroscopy (NMR), and visible and ultraviolet spectroscopy (visible-UV);
• matching analytical technique/s to a particular task

Quote
AREA OF STUDY 2 - Organic chemical pathways
• structure and systematic nomenclature of alkanes, alkenes, amines, chloroalkanes, alkanols and
carboxylic acids up to C10;
• common reactions of organic compounds: addition reactions of alkenes, substitution reactions of alkanes and primary chloroalkanes, oxidation of primary alkanols, esterification;
• principles of fractional distillation;
• organic reaction pathways including the production of esters from alkenes, condensation and polymerisation reactions that produce large biomolecules;
• primary, secondary and tertiary structure of proteins and the function of protein catalysts (enzymes);
• biochemical fuels including fermentation of sugars to produce ethanol;
• the structure and bonding of DNA and its applications in forensic analysis;
• use of proteins as markers for disease;
• function of organic molecules in the design and synthesis of medicines including the production of aspirin from salicylic acid.

You should probably set out a few hours this week to get back up to speed with the concepts. You can go back to the theory - reading the textbook, trying to take in the general ideas/principles. Don't set out to write detailed notes - probably a waste of time at this stage, but when you're reading the book, actively read, scribbling down extremely rough notes and drawing diagrams and thinking about concepts at the same time. Two birds with one stone pretty much.

Also for the general ideas, you can take a look at some of the notes on AN (http://www.atarnotes.com/?p=notes&search=&subject=Chemistry&units=MyY0), particularly take a look at the Unit 3 summaries.

I would try to move back to smashing out the questions soon enough, but getting your head around the basic ideas first will have it advantages.

Another quite important point is to talk to your teacher, ask them for help, see what they say.



For things that cost money (you can easily get by without these though):

- Study Guides, same as the others, I'd recommend the AN study guide written by Thushan. The solutions walk you through each question, explaining theory as it goes, so it's quite handy. It's something worth considering to purchase.
http://www.atarnotes.com/?p=estore&a=view&id=2

-- Otherwise, take a look at the school library or local library, they might have a few study guides for chemistry.

- Tutor: dunno, sitting down with someone one on one might be useful, depends if you like that style of learning or not

- Revision lectures: They're all in the next couple of weekends, I'm not too sure but you might not get too much out of them if you're not up to speed with stuff in the first place. Also, a lot of them are overpriced and expensive. If cost is an issue, there's the free Victoria Uni revision lectures.



Once you move back to practice exams (after re-familiarising yourself with the basics), my opinion would be to go all out on the VCAA exams (2008 to 2011) first. This is opposed to the approach of doing other company exams first and then leaving VCAA for the last few weeks to gauge how you're fairing.

It's really important to measure yourself against that VCAA standard and ensure you're up to it - and if not then there's still time to get there. Also, pay attention to the assessor reports, particularly noting the common mistakes that students make - that all goes back to the stage of refining your understanding once you've grasped the basics though.

There's plenty of very good videos on Youtube with detail many of the concepts relevant to VCE Chemistry. And of course revision lectures would be very handy; Access, Connect and Engage Education are hosting chemistry lectures for $40, $49 and $52 respectively.

Hey man at least you've started practice exams hehe.. but don't worry just go over the theory again.. I recommend watching videos and reading http://www.chemguide.co.uk/ the concepts are explained beautifully.. also get the AN exam study guide if you can.. even if you can't do the questions.. the detailed solutions are so great that it is very easy to learn from the solutions themselves!

goodluck! and I'm sure you'll do well.

Thanks all for the replies, particularly laseredd for the comprehensive post!

Ahhh, I'm really feeling like an idiot. The whole "back to basics" thing really hits hard, but I see now its probably the best idea  :-\

As for notes, I've already had a look at the summaries posted on AN and have compiled some basic ones myself. Will probably purchase the AN study guide tonight as well. Checkpoints is great, but I'm honestly doing poorly in it as well (a la, getting more wrong than right)

So basically, in the next week I should be simply reviewing the theory and concepts, going over notes etc. AOS1 is definitely my weakest point, which means more effort will probably go to that area.

I started doing a couple of exams last week and did dismally. When combined with how horrible I just went on another, I think I'm screwed.

If I'm getting like 7/20 for multi choice and flunking the short answer, where do I go from here?

First and foremost, do not panic!
Coming from a guy that had a massive panic attack over not being able to do ANY spectroscopy and chromatography, you can pick yourself up!  At first I got heavily paniced and shut down for about a week, it's literally the worst thing you could do.  It's great that you've identified that you're struggling, and as Laseredd suggested (he is amazing at fixing things, IRC perhaps? :P ) try addressing each point in the study guide, there's a crap load of stuff teachers and the textbook use to try and expand your knowledge that isn't exactly relevant.  If you build yourself up from the foundations of each dotpoint, you'll be able to drastically improve your scores.

Interms of motivation, if you're similar to me in anyway, you'll probably be feeling really demotivated.  Just aim to study more consistently rather than in bursts, for me, I've made flow charts on specific procedures to follow for the combination of the MS, NMR and IT techniques, which are stuck on my fridge, toliet door, shower and even in the car :P

Please, watch this video and then get to work

We definitely don't mean to be hurtful, but the basics are truly the best thing! Chemistry is one of those subjects where you just need to apply a few concepts to an entire area of study. As someone else suggested, spend as much time as possible reading the chemguide website. I see things on there everyday which just make me go 'duh', but I hadn't actually realised them before.

And remember that whilst you're "stressing like there's no tomorrow", there definitely is, and about 22 other tomorrows after that! There's heaps of time left until the exam, so work hard, but take it easy (:
