There you go!

Just wondering, is there one of these forums for C3 and S2?

Also just a quick revision method question, do you guys find that you revise only one subject at a time? For example spend a few days on maths then something else or do you timetable different subjects into the day?
Im asking because I have a lot of revision to do for my other subjects which I have neglected but I fear that I may end up putting maths off till theres only a few days before the exam.

Here's the link to the core 3 thread:

I'm not sure about S2. I've only set up C3, C4 and M2 as those are my only units. Sorry!

I tend to revise multiple subjects per day. Little and often helps a lot. It's not how long per day you revise that makes it effective, it's how often you revisit it in my mind. Just my opinion though

Thanks for that.
I might give your method a try but i still have a lot of chemistry to get through...... 😨

Ah no! What subjects do you do -maths, chemistry..?


Posted from TSR Mobile

Maths
Chemistry
Business

Until now I have just spent my time outside of lessons on maths. Business isnt too hard to graspe but I honestly cant remember much Chemistry so atm im trying to teach it all to myself again quickly.

What about you?

Posted from TSR Mobile

Oh nice! I do Maths, Physics, Computing and History. It's going okay, just a lot to still remember haha.

Does anyone know if we get marked down for being out by like 0.001 on the trig solutions with an obvious correct solution? Because sometimes you lose accuracy when you find say cos(2x-10)=0.4 to 3sf because when you divide your values by two you can get slightly different values to the MS.
Is that ok or should we always do it to a higher sf in calculation? (Sorry for the poor explanation!)

Also does anyone use the CGP C4 book...? If so chapter 2, part 4 on the factor formulas, is that actually in our spec? Because I have never seen it on a paper!

That's the first page and then an example. Have seen the formulas in the formula booklet but have never seen anything like the example on any past papers!

Okay that has well and truly freaked me out. I wasn't aware of those. I'll ask my maths teacher on Monday!


Posted from TSR Mobile

I know it freaked me out... But I've never seen it on any papers so was wondering if it was new :/ The book is new, but it is the AQA C4 book so should be reliable!

Can you tell me what your teacher says when you ask him?
