Dear aspirant;

for preparation do prepare for following;

1. a 2 dimensional drawing mostly comprises of compostion of circles, squares, triangles and rectangles (2d shapes), forming an abstract figure by fusing these shapes, they are already drawn (generally left side), and u need to draw their mirror image (reflection image), on other side without using scale or ruler, free handed.

-- try practicing drawing straight lines and circles free handed without scale or compass, (you will find tutorials on youtube for free hand sketching).

2. u are required to draw a composition of 3d solids generally  cylinders, cubes, spheres, . no and requirements are provided with ques.

--- try practicing drawing 3d solids, search on google (keywords- 3d solid compostions, cylinder and spheres, cubes composition) PAY ATTENTION TO LIGHT AND SHADOWS. assume light from left side generally or as per given in question. if ques says light is falling on angle of 45 degree, dont paninc thers no calculation or measurement , u just need to draw lenth of shadows equal to height of objects. CAREFULLY ANALYZE THE SHADOWS CAST BY SOLIDS. practice drawing solids with shadows and shades. google them ull learn to know.

- last year it was not a 3d but a 2d question, draw a compostion with no of pentagons. ( it depends they can set any 2d or 3d question)

3. a large question of full page contains max marks. it may be anything. few of the last years questions are

- suppose u are playing in a park, u see slides, shrubs, hedges and flowers, children are playing and people are walking. draw a scene

- sketch portrait of your favourite bollywood film star ( try practicing amitabh bachchan, and srk their facial features are unique ).

- suppose u r stading outside a park's wall . a 'ballonwala' is giving ballons to children . draw what u see.

- suppose u are watching a basket ball match seated in audience. draw what u see.

carefuly study human figure drawings, facial expressions and practice stcik fugures to draw humans in different poses. U NEED TO DRAW A COLORED SCENE. USE ONLY PENCIL COLORS AND BIT OF FINE POINT TIP BLACK GEL PEN TO OUTLINE FEW PROMINENT FIGURES. uupencil colors are neat and clean to use. (I personally recommend FABER CASTLE or STEADTLER PENCIL COLORS only). have a glance through sketch book a good school children of 6th 7th 8th class. and their practice drawing books.

Thank you.

First of all before going in for some study material awesome coachinginstitute you do need to realise and analyse that what kind of a person you are if you are more of a self study guy who can spend time alone and dedicate himself to studying by himself then this is the best for your own welfare and you can just go ahead and pick up some good quality books from publishing houses like Arihant or Tata mcgraw Hill. If you are taking a drop year or you still have 2 years to prepare kindly go through the books entirely and very thoroughly in order to analyse and understand each and every concept all that were very way to the core . Now if you are the second type that is guys who do not have the constant appetite to roam around and not sit at a specific place and keep studying by themselves if you are going in for a coaching do take care of the very fact that you have enough time to prepare their entire thing that they taught you by yourself because without that it is just like applying a plaster over  a wound without any medicine. You do need to that to qualify JEE mains you need to have high order thinking skills and a deep understanding of all the concepts regarding each and every topic because people from big institutes come and set the entire paper duration just because of the lack of concepts.
