For the first 15 days revise the topics of each subject as much as possible, review formulas, concepts, shortcuts and then go for topic wise, subject wise and all India mock tests. You'll get to know where you stand, accordingly you can still push your limits. Last month of preparation is crucial for every aspirant of GATE. So, its time for revision of topics and writing as many online mock tests as possible. Hope this helps, thank you. «less

Hi Uma,
I suggest you not to take up project management as it'll keep you away from designing.
Instead there are various options like landscaping, conservation, urban design which are related to architecture.
You can select anyone that you think you are interested in.
I hope I've been of help.
Good luck dear.

For the Advanced paper, If you start just after you complete Class X, you should be able to complete your preparation before you sit for your Class XII exam- provided you are serious, and work methodically with a good guide. It will help if you brush up on elementary calculus and trigonometry in class X itself.

Resistance is a measure of the extent to which a substance opposes the movement of electrons among its atoms.The more easily the atoms give up and/or accept electrons, the lower the resistance, which is expressed in positive real number ohms.
Reactance, denoted X, is an expression of the extent to which an electronic component, circuit, or system stores and releases energy as the current and voltage fluctuate with each AC cycle. Reactance is expressed in imaginary number ohms.It is observed for AC, but not for DC.When AC passes through a component that contains reactance, energy might be stored and released in the form of a magnetic field, in which case the reactance is inductive (denoted +jXL); or energy might be stored and released in the form of an electric field, in which case the reactance is capacitive (denoted -jXC). Reactance is conventionally multiplied by the positive square root of -1, which is the unit imaginary number called the j operator, to express Z as a complex number of the form R + jXL (when the net reactance is inductive) or R - jXC (when the net reactance is capacitive). «less

In a discrete-time signal, the number of elements in the set, as well as the possible values of each element, is finite, countable, and can be represented with computer bits, and stored on a digital storage medium.

In vector calculus, divergence is a vector operator that produces a signed scalar field giving the quantity of a vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.
As an example, consider air as it is heated or cooled. The velocity of the air at each point defines a vector field. While air is heated in a region, it expands in all directions, and thus the velocity field points outward from that region. The divergence of the velocity field in that region would thus have a positive value. While the air is cooled and thus contracting, the divergence of the velocity has a negative value.
In physical terms, the divergence of a three-dimensional vector field is the extent to which the vector field flow behaves like a source at a given point. It is a local measure of its "out goingness"– the extent to which there is more exiting an infinitesimal region of space than entering it. If the divergence is nonzero at some point then there must be a source or sink at that position. «less

Divergence of vector indicates how much resultant vector quantity diverges or converges a given volume. For example water flowing in a pipe per cubic centimeter is the best example of divergence.
