I'm currently doing two level 1 courses and one level 2, 90 points altogether. Bit different for me though since the majority of the level 1 courses is stuff I already have some knowledge of and I haven't had to put much work into it at all.
In your case though it would probably make more sense to do two level 1s followed by the two level 2s, if that's what you're going to end up taking in the next 2 years anyway (assuming that'll be similar amounts of points each year?), although I guess it depends somewhat on the courses & what your current level of knowledge is.
