Predictions for the 4s?
Struggling to find what to prioritise because barely even studied the standard demand since we only had around a week to squeeze in biology physics and chemistry :/
Revision tips for science? xoxo

Spending Wednesday afternoon revising biology, whole of Thursday revising chemistry and physics and Friday morning going over everything again. Hope it works out.

I thought the paper was pretty decent for us, like easier than 2014 paper. it asked about concentration in particle model, atom economy. respiratory quotient, % yield, b3 asked symbol equation for aerobic respiration, dna replication on 3 mks. Nothing on cloning which was good and most ppl find hardest. P3 was easiest, car safety features, GPE q, Power (work done) formula used in question. Atom economies for one was 69%. and 75% for 6mark c3 q - you had to use Energy transferred equation and rearrange it to get temp of water. I know its right cuz it has to multiply in to get u SHC. Q on why grapheme conducts elec. was easy - layered structure of carbon atoms doesn't contain delocalised electrons/ions so they cant carry current. p3 6 mark comparison was easy. Overall I think the paper was great for me, hoping for an A* realistically. Hope the Unit 4 paper will be easy, but I know they'll make it hard hence its longer time. What other q's was there? I lost 2 marks on balance the chem.reaction. only silly marks I made.

There's also gonna be a section D, so good luck with that xo
Found it quite annoying how there wasn't anything about plants because was rather looking forward to it
Made a few silly mistakes regarding the equations uuughhhhh
