hi reading section was a problem fr me too whn i started off.. But here r few tips
1: Never read the whole passage at a single go n thn try to answer questions... In most instances the passagwes dont make much sense.
So always read the first q thn u know wht thy r asking so u can just scan fr the answer in tht passage.
2: If u can read a couple of gre books fr reading it would be gr8.. For instance the reading comphrehension of gre. If u do tht n thn come back to topefl reading.. Reading bcomes a cakewalk.
3: For speaking practice speaking using the voice recorder on u r pc set it fr 45 sec/60 sec so tht u can pace u r self.. Always listen to u r recording ... Coz while speaking we do not anticipate the mistakes we make only whn we listen we can anticipate our mistakes. Lastly try to keep it simple n reasonable. Use synoyms to if u hv academic lecture to show tht u have understood the topic n can put it in u r own words. Dont use the same words of the lecture in speaking!!!
Writng : Always spare amplle time fr proofing readinf at least 2 trimes coz one reading we may miss many mistakes.
