First of all let me compare AIEEE with JEE in the following respects:

1 Type of Questions: In JEE questions are heavily concentrated on fundamental concepts,while that of AIEEE’s Questions are based on mugging* and practice.

2 Time per Question: In AIEEE time per question is =T/nQ=180/120=1min 30sec per question,on the other side in JEE this comes out to be 360/135=2 min 40 sec per question.(on average)

3 Nature of options : In JEE we can use dimensional analysis or such methods to cut out at most two options but still there are remained 2 options of very similar formation n presentation.In AIEEE after using dimensional analysis etc mostly only one is left which is correct 99%(if you have done it correctly)

4 Rough space : In JEE they provide us a lot of blank space it is approx 10800(20 pages x 27cm height x 20 cm width) cm2. for 135 questions ie. 80 cm2 for each question which is sufficient.on the other hand in AIEEE it hardly comes out to be 200 cm2, ie less than 2 cms for each question !!~! (how one can solve Q in such a tiny space ? are bhai it is just AVERAGE)

5 XYZ : mentioned at last of this article

so ? here comes the conclusion :In JEE examiner wants us to convince ourselves completely and be 100% sure before ticking any Answer ! on the other hand In AIEEE all the points mentioned above agreeing with the fact that examiner don’t wants us solve each n every question* !!!! (wow!) so here comes the “KEY” the “BRAMHASTRA” for AIEEE ( ie don’t wants us solve each n every question” )
so,let me now describe “how”to mark the right”bubble” without solving it completely ! the approach can be divided in to following heading for better understanding:

1 Check the Ans : This is the most powerful method with which you can even answer what you actually don’t know ,works equally well in all test JEE AIEE n other competition
working:
just put value from the options in the equation given(if any) or check if it does satisfy all the necessary conditions given in question.

2 Dimensional Analysis : mostly used in physics and chem(can also be used in maths) In JEE as I’ve said earlier works not so well but still if used will not be harmful as it does increase the probability from 25% to 50%(by cutting off two options)

3 Interpretations : In any particular formulae iff you you know “What is What” you can easily use this method for separating one particular option from other!
for example in eq : x2 +y2 +2gx + 2fy +c=0 ,
g is what ? ie -tive 1/2 of co-eff. of x is what ? (huhn? yes it is x co-ordinate of centre of the circle described by eq)

4 Using “NON- COMMON ” standard values : useful in maths (particularly)
can be used in physics(almost no scope in chem) before going into its working NOTE that i have given emphasis on NON- COMMON , if you still use too common values you are definitely going to put yourself in trouble !
working:just replace all arbitrary constants with something like 3,2,1(not 1,2,3)
or -3 -2 -1 0 etc

5 Chem: MOST PROBABLE LOGICAL TUKKA : )
In this method one option is separated by other ,by using all above mentioned methods and specially bu using Ur IQ

working:Let me give example
Q) Which of the following Nitrates does not decomposes on heating ?
a) Pb(NO3)2 b) Ag(NO3)
c) KNO3 d) Cu(NO3)

Here we can see that all are heavy metal nitrates accept for KNO3 and MOST PROBABILY this is the ans . YES ! this is in fact correct !
