It cant be B? as 50% is AS level and 50% is A2 level?
so in As he scored 76 so in A2 he should score 84% right?

Yes, it's like 50% in AS and 50% in A2. So the total marks for A2 level are 130, and for AS are 130. He secured a total of 172/260 (combined). According to the gts, the A* is at 178 sth. where as a B starts at 138 sth. So it is definitely not a B.

So generally u give in parts or all together, there is no much difference in GT?

Yes, not much difference here but sometimes there is a great difference, like if you see the gts for 2016 May/June Chem, the A* for those who gave all 5 papers together, the thresholds was in 170s (I don't remember the exact figure) but for those who gave in parts, the threshold was high like in 190s! But it happens very rarely though :p

in this year, The gt for an A* if you give all 5 papers was at 191, where as for those who give in parts, the gt for A* was at around 180sth (depends on in which session you gave the AS portion papers)

Suppose one gave it in November 15 and scored 76 in AS level.
So in A2 he gave in may 16. What will be A* at for that person? :D like how much should he/she score in A2 papers? :D

Fleming's left hand rule for the motor effect. Magnetic field, Current and Force are at right angles.
Is the current considered from positive to negative (conventional current) or from negative to positive?

The seCond finger represents Current. Keep the second finger in a way that ur nail point in the direction of current.
When the particle is electron(-ve charged particle), we take opposite directions and when there is positively charged particle we dont need to bother about changing direction, keep the finger in the dirrection shown in the question. In wire as well, oint the finger in the direction of current. :)
