               Quantitaive task-worth15marks:(carry out a pratical task using instructions supplied by OCRand then doing detailed calculations questions)

               Evaluative task-worth15 marks (in this seaction i have to evaluate an experiment)

how do i..
-recognise trends in a data and identify anomalies
-reach valid conculsions
-assess the reliabillity and accuracy of an experiemnt task
-identify significant weaknesses in the procedure ad measuremnt
-understand and select simple improvemnts to prcedures and measuremnts

can you please give me some tips and some ideas on how should i improve the experiment or has anyone done the experiemt already??

These things are very subjective, and a decent treatment would occupy pages, that some poor forum regular would have to type in by hand.  Do you have any ideas of your own, that we could help with?  Failing that, maybe you should try to find some info along these lines in your textbook, or check the library for a university level text.

Nothing I can post on this forum can fix putting the wrong fluid in the burette, we have yet to develop fluid transfer via TCP/IP.   Try to write out what you have to do, in outline form.  Or maybe play with the glassware before hand, using just water, to improve your technique.

The A-levels are supposed to be difficult, not everyone gets them easily.  Try to plan out your tasks, so you're not flustered.
