Four things are due before Thursday and one deadline outside school is closer than any of them. Estimated total 78 minutes — under your prep hours.
Your draft says you want to build things. It does not yet say what you did about that. Paragraph 3 is doing no work — it restates paragraph 1 in different words.
A block of copper of mass 0.150 kg at 95 °C is dropped into 0.400 kg of water at 18 °C in a polystyrene cup. Specific heat capacities: copper 385 J kg⁻¹ K⁻¹, water 4180 J kg⁻¹ K⁻¹.
No quiz produced this. Each bar is the last three pieces of assessed or drilled work on that topic, weighted to the most recent. Empty means not taught yet, not failed.
Returns an examiner-style report: where marks were lost, which command terms you answered as if they were a different verb, and how long each question took against the mark tariff.
UCAS and the Common App are not two versions of the same form. Filling one the way you fill the other is the most common expensive mistake made here.
Eleven attempts break at the same step of part (b): ΔT for the copper is equated to ΔT for the water, which quietly assumes m c is the same on both sides. Four then averaged 95 and 18 to get 56.5 °C. Rung 2 unstuck seven of them; three escalated; one stopped at 23:12 without submitting.
The same assistant that sits inside your work, with a door of its own. It still starts from something real — pick what this is about, and it will tell you what it is allowed to do there before you type.
