comment A group $G$ with $|G|=p^3q$ and with no normal Sylow subgroups is $G \cong \mathbb S_4$
Suppose $1+kp=q$ and $1+lq=p$ this would give $1+k(1+lq)=q\Rightarrow 1+k+klq-q=0$.. Do you see something wrong?

comment Soft question regarding real analysis
Start with first chapter.. It is so important.. Try reading second chapter and if you feel some difficulty may be you can skip that in first reading... Then, Sequences and series continuity, differentiation all are important... Do not dare to miss even one section in these three chapters... May be this is enough for something like 3 months self study course.... try looking at riemann integration part also..

You don't have to do that either.... you might get a down vote....
